Just for the context UBI kind of already exists in some countries but in a different form. If you are in Ireland and do not work you get the benefits provided you have somewhere to live and can pick them up in the post office (~200eur/week). The problem is that it solves only part of the issue because people have to live somewhere, and sure the gov will even contribute towards it (they do already) but somehow not enough is being built. The benefit is basically not enough to get the mortgage, nor is there housing available.
