I apologize if using hyperboles makes my point less clear. I'm not literally advocating Alaska, I'm trying to make the point that cities as we currently know them only exist because they are the most efficient solution when the population mostly has to work in the same location. Once you remove this constraint, it's much more viable to have smaller and more distributed population centers, without necessarily resorting to living alone in Alaska. This would still significantly reduce rents, and even better allows competition between distant locations which wouldn't otherwise be competing on prices.

For the other point, UBI as I know it must be financed by some sort of increased taxation of the rich, it is not the government blindly printing money and distributing it. I don't know whether that taxation should be LVT or something else, I'm simply talking about why the argument that UBI doesn't work due to rent is, in my opinion, incorrect.
