Earlier quoted context omitted.
Land is a finite resource that nobody created. Would you be offended if someone claimed to own a cubic kilometer of the sky and declared nobody else could use it without paying him?
Land is a finite resource, but buildings can be built up vertically. Unless your town looks like manhattan, land is not scarce for new housing.
Just for the record, building vertically is also a finite solution, just as building sprawl is horizontally constrained, so to is vertical ( and subterranian ) expansion.
Manhattan only exists due to Manhattan schist, exceptional bedrock due to old volcanic flow.
Many locations have poor subsoil for tall buildings, even with the best foundations there are other limits to building height.
There's a lot of potential space, sure, but not infinite space - it's finite on planet and bottlenecked by transport and terraforming off planet.
