In a way, this is how property ownership works now. "Owning a home" is a license from the government. Obviously, you're license will be revoked if you don't pay taxes. Also if the government is overthrown, your deed won't be worth much. (ask a Palestinian).
I've always thought it was weird that a person could own land. This is a ridiculous idea from a geologic perspective. IDK if it's real, but I've heard that Native Americans though that a person claiming ownership of the land was like a flea claiming ownership of the dog.
The government doesn't set the price of lots or land, that's determined by the seller. A deed will still be worth its value unless total lawless anarchy takes over. If the government is overthrown, the price of land is only effected by the stability of the currency.
I guess OP meant won’t be worth much as in „when your government is overthrown, the new government might just kick you out of your home and strip you of your land“ as the current government is actually the only party giving you the right to claim ownership of the land.
Ownership is a legal fiction that doesn't exist outside government.
Being able to occupy or defend something isn't the same as owning either. A bear can defend it's territory without property rights. A goose can shit in your front yard without an easement.
Unless you live in a slightly more evolved country, where a simple ownership transfer is not enough to kick out the renters and you actually have rights. Here you need to prove that you either want to use it for yourself ( 2 years minimum, government checks up on that) or it is somehow damaged beyond repair.
It's rather common here that people get paid 10-100k euros just so they move out of an apartment ( this is per flat/apartment, so numbers can get huge for bigger buildings) and the owner can sell the empty old building to an investor/developer. Shows what insane profit margins are still to be had, if they make profits despite that.
This usually happens with old and cheap buildings in now gentrified, suddenly fancy neighborhoods.
That's rental though. This really does happen though, buying a leasehold but not the freehold is basically buying a licence to live in your house from the person who owns the land.
“It is my sad duty to inform you of a four-foot restriction on humanoid height.”
“I hear the directors of Genetic Control have been buying all the properties that have recently been sold, taking risks oh so bold. It's said now that people will be shorter in height; they can fit twice as many in the same building site (they say it's alright). Beginning with the tenants of the town of Harlow, in the interest of humanity, they've been told they must go—told they must go-go-go-go.”
