The housing:land demand ratio is also not fixed, due to multi-level dwellings (hence, for example, Singapore or Hong Kong), or increased density (e.g. ADUs or smaller lots).
I just don't see why you see UBI only affecting owners of a nearly-inelastic resource (land) rather than everything else too (even if to a lesser degree) ?
So same mechanism applies to land, except then there’s no way to spur additional production of land, so the price just goes up.
Re density etc: correct, which is why I’m not arguing this benefits homeowners or building owners, except to the degree they are also landowners. A building owner who does not own the land underneath his building would not benefit much, the person who he pays land rent to will capture nearly all of the upside.
