I think this is a bit premature because there is usually some form scarcity either by distance or time and a medium of exchange is necessary to trade these resources

e.g. gold is scarce localy but a sufficiently advanced space mining system will increase supply until we need to get out of the solar system, then you likely have to time constrained scarcity ie have to wait for operations in another star sysytem to be setup and send resources back

Even considering there are billions of people and perhaps a few very disirable places for them to live, how to allocate living space equitably since the qualities that make that space desirable cannot easily be scaled e.g. the historical / cultural value of living in Paris, the beauty of living in Hawaii
