I’m a member of a quasi-historical recreation group. One of the biggest events of the year is known as Pennsic. 10,000+ of us converge each year on a farm in Pennsylvania. By necessity, space is allotted on a by-person basis. When you reserve space, you’re granted 100 square feet per person.
This does two things: 1: assures everyone gets some space, and the one guy who owns four Marquee pavillions doesn’t take up the space of 30 people, and 2: it encourages people to camp together. If you get 5–10 people together you can put up bigger individual tents, and even have space left over for communal sitting space, campfires, etc. If four people sleep in one 10X10 tent, that’s another 30X30 space you can use for whatever, including accommodating people who couldn’t pre-register (guests, last minute friends-dragged-along, etc.)
It’s a good system, for what it is. There are always people who complain that they really really want to set up their 5-person-sized tents, but those people are always more than welcome to pay five site fees to do it. However, there are limits placed on over-buying land, and if they predict an overselling of land during land-grab week, people who overbuy will be refunded and instructed to take their smaller space.
It’s a system that works for the self-selecting community.
It wouldn’t work in society as a whole, I’m afraid. There’s always going to be someone with the means to buy their way into more space than they need.
