Like, how do the Picards get to keep their bigass vineyard? Do they supply the public with free terrible wine in exchange for this massive piece of land? Can anyone walk around there? Could they pick some grapes for themselves? Who is tending this vineyard, surely not just his weird brother, and especially so, who's tending it after they die in generations? How did Sisko'a dad get the restaurant property? Sure there's technically limitless space cause you can go live on some colony, but those always seem to be weird semi agrarian weirdos or a single town with a staircase that leads no where in the center. I demand to know how the federation does real estate!
My guess is that the state, maybe at the level of the city of New Orleans, owns the land and leases it out to business-people for productive use, judging on a case by case basis what best serves the community. A Creole restaurant run by a master chef is a good business to have in New Orleans as it helps preserve the local culture and gives people a good place to eat. And I'm using the term "business," but in a future without money, businesses would not be run for profit, but because they serve a perceived greater good.
I could see that as well. But like...what about housing and stuff?
Maybe a mixture of private and public housing, with a constitutional housing guarantee?
