Four novelists put a colony on a moon. Heinlein's ships grain to Earth until it revolts. Le Guin's walls itself off and stops changing. Robinson's gets carved up by whoever landed where. Suarez's pays everyone on Earth a share. The real rules for our Moon were written in 1967, and they're quiet on exactly the part that matters.
The rock is the same on every moon in fiction. The rules about who can claim it decide whether a mining colony ends in a revolt, a wall, or a dividend.
What money is a claim on ends on a warning about the orbital system: “The issuing class and the working class end up on different planets.” That page asked what money should be backed by. This one asks the question underneath: who gets to claim the thing in the first place?
Pick a rulebook and watch where the value of one ton of lunar ice lands. Then write your own rules and see which story they turn into.
One ton of lunar ice
NobodyNationsCompanies

Five places the value can land: the nation that launched the operator, the operator's shareholders, the people working on the Moon, everyone on Earth (a dividend or a commons fund), and the future (ice left in the ground).
Your rules: the first two answers pick a starting split. Nobody claiming and nobody issuing leaves the ice in the ground. An authority on Earth issuing money tilts value toward the claimants; stakeholders issuing it tilt value toward the workers and Earth. The world fund then takes its share of everything mined. The closest story is whichever of the six rulebooks is nearest.
The splits are illustrative readings of each book and law, not economic estimates. The CCE is Suarez's invention; the trainer is an unofficial fan project.
Four moons
Each book takes the same setup, a colony on a moon that ships its wealth to a planet, and changes one rule: who holds the claim.
The Moon Is a Harsh Mistress
Robert A. Heinlein, 1966. The claim sits on Earth.
Who claims
The Lunar Authority, run from Earth.
Where it goes
The Authority buys Luna's grain at prices it sets and throws it to Earth down a catapult.
How it ends
Luna declares independence on July 4, 2076.
Mike, the computer, works out what the trade really ships. The ice that waters the wheat never comes back. Keep exporting, he calculates, and there are food riots in seven years and cannibalism in nine. The book's case is that the trouble was never the rock.
“This planet isn’t crowded; it is just mismanaged”
Robert A. Heinlein, The Moon Is a Harsh Mistress, loc 4095
Where it broke.The people doing the work had no say in the price, and the water left with the grain. A claim held on another world drains this one.
The Dispossessed
Ursula K. Le Guin, 1974. No claim at all, and a wall instead of a market.
Who claims
Nobody. Anarres, the moon of Urras, was settled by Odonian anarchists about 170 years before the story. They own nothing.
Where it goes
A few freighters land inside a walled field, the Port of Anarres, near the city of Abbenay. They carry metals and ores to Urras.
How it ends
The physicist Shevek crosses the wall to Urras, and comes home.
On propertied Urras, Shevek finds everything priced.
“There is nothing you can do that profit does not enter into,”
Ursula K. Le Guin, The Dispossessed, loc 5069
But back home, nobody is exploited and nothing moves.
“Change is freedom, change is life—is anything more basic to Odonian thought than that? But nothing changes any more! Our society is sick.”
Ursula K. Le Guin, The Dispossessed, loc 2424 (excerpt)
Where it broke.The wall kept the rentiers out, and it kept the ideas out too. No claim is fair to the workers, but a wall is no way to trade.
Red Moon
Kim Stanley Robinson, 2018. The claim goes to whoever is standing there.
Who claims
It's 2047. China has the biggest presence on the Moon, around the south pole. The Americans and everyone else are clustered around the north pole.
Where it goes
To the nations holding each pole. The Moon is a board in a contest between China and the United States.
How it ends
The decisive events happen back on Earth, in a huge demonstration in Beijing.
Nobody plants a flag. They don't have to. A base, a landing pad and a head start do the same work.
Where it broke.The Moon had no politics of its own. Whatever Earth was fighting about, the Moon was fought over.
Critical Mass
Daniel Suarez, 2023. The claim is spread across stakeholders.
Who claims
The Cislunar Commodity Exchange, owned by the people who earn a stake in it.
Where it goes
Split across stakeholders, with lūna, the Exchange's currency, issued against real assets. Anyone on Earth can earn lūna for pulling carbon out of the air.
How it ends
The book stops at the beginning, with the Exchange running.
“A founding principle of the CCE is that the entire population of Earth should benefit from space industry, not merely a few billionaires and powerful nations.”
Takeaway.Same rock, four endings. The difference is always the paperwork.
The real rules
Our Moon has rules too. Most of them were written to stop nations, not companies.
1959The Antarctic Treaty is signed in Washington on 1 December. A whole continent is set aside for peace and science.
1967The Outer Space Treaty, Article II: Outer space, including the moon and other celestial bodies, is not subject to national appropriation by claim of sovereignty, by means of use or occupation, or by any other means. No nation may claim the Moon.
1979The Moon Agreement calls the Moon and its resources the common heritage of mankind. It is ratified by 17 countries, none of them major launching states. The US, Russia and China never join. France and India sign but never ratify.
1991The Madrid Protocol to the Antarctic Treaty, Article 7: Any activity relating to mineral resources, other than scientific research, shall be prohibited. In force from 1998.
2015The US Commercial Space Launch Competitiveness Act: a US citizen or company that recovers a space resource is entitled to it, including to possess, own, transport, use, and sell it. The title is to what they dig up, not to the ground.
2020The Artemis Accords, first signed by eight nations on 13 October. Section 10 says extracting space resources does not inherently constitute national appropriation under Article II of the Outer Space Treaty. More than 75 nations have signed by September 2026.
2024Saudi Arabia leaves the Moon Agreement in January, the only country ever to withdraw. It had signed the Artemis Accords in 2022.
The one treaty that tried to say who owns the Moon's wealth is the one the launching nations stayed out of. The ones they joined say nations can't own the Moon, and companies can own what they take from it.
Takeaway.The treaties stop flags. They're silent on companies, and on what the ice is worth.
The rentier on the Moon
In The Ministry for the Future, Robinson borrows a word from Keynes: the rentier. A rentier makes money by owning something other people need and charging them to use it. Rent, in this sense, isn't payment for making anything.
The Moon's most useful ice is thought to sit in a few permanently shadowed craters near its poles. Ice is drinking water, air, and rocket fuel, all in one. Whoever holds the only ice at the south pole holds the purest rent there is: a toll gate every ship has to pass.
“Maybe feudalism never really went away. Maybe it just liquefied to money and bided its time.”
Kim Stanley Robinson, Red Moon, loc 5480
Every ruleset on this page either creates a rentier or prevents one. Try it on the bar: Finders keepers hands the ice to whoever got there first. The Antarctic rule leaves it in the ground. The CCE splits it.
Takeaway.Owning the only ice isn't industry. It's rent.
What a fair claim looks like
A fair claim pays the people who do the work and leaves a share for everyone who didn't get to go. There are three working models to borrow from.
The CCE. Suarez's Exchange spreads the claim across stakeholders and issues lūna against real assets. Its stakes can't be bought; they're earned over seven reliable years.
The carbon coin. In Ministry, central banks pay for every ton of carbon kept out of the air. It pays whoever does the work, not whoever owns the most already. What money is a claim on sets the two side by side.
Mondragón.Ministry names it as a model. It grew from Ulgor, an industrial cooperative started in 1956 in Arrasate-Mondragón, in the Basque Country, under the priest José María Arizmendiarrieta. Today the Mondragón Corporation employs more than 71,000 people. Not all of them are member-owners, but the cooperatives are owned by the people who work in them, and it has lasted seventy years.
Takeaway.The geology doesn't decide fairness. The paperwork does, and the paperwork for the Moon is still being written.
