Energy, time and space.

Distance is effort, both in energy and time.

Space is already constrained by historical distributional of 'valuable' lands, and restrictions on new ones. There's nowhere left to go out and just settle that someone else doesn't already claim somehow. (Yes, if you go out of the solar system you might claim that... but that's literally how bad the issue is.)

The real solution is increasing supply. Yes, UBI will help individuals, but society must actively balance to ensure that there is enough supply in the markets to maintain liquidity. Otherwise (as we see with housing) flow seizes and prices dramatically rise.
