If a country said “all real estate owners are now the sovereign heads of state on their property” that would create a new class. This is very different from the “people are replaceable” situation. Micro-sovereigns own their land.
A different sort liberty with more Georgist influence or the Lockean proviso might be “to claim exclusive use of a limited natural opportunity like real estate or radio frequencies, you need to pay rent. This pays for some public goods or a citizen’s dividend.” This is a very pure antithesis of the micro-sovereign situation because even though it is still a market-based economy people are just replaced if they aren’t good enough at playing the market game. If someone bids more for the land, they get to rent it and you don’t. If someone else is better at subsisting off their citizen’s dividend, they can outlast you.
Proposals closer to the micro-sovereign model are just pleas for us to start over. The region gets more decentralized for a while.
Proposals closer to the Georgist model are more sustainably fair, but that fairness means the precise details of the system determine what kind of people can live in it. It could be an elite meritocracy, but it could also be the great replacement.
