There is nothing innate about this state of affairs. What is "ownernship"? How many acres of land and I keep to myself with my own shotgun? Surely that's bounded too?

Every person deserves some amount of floor space near other people's floor space. They do not so deserve private land area.
Land area is held in common in parks, whose size, beauty, and other factors vary inversely with their accessibility. We can vary the park distribution and the vacation distribution to do nice things with the expected nature rejuvenation.
This is completely separate from housing.
