I have difficulty believing that UBI will ever work, unless you get the basic problems solved first. Namely, housing. The problem actually boils down to democracy itself, where people vote for laws that favors themselves, and excludes outsiders, specifically the NIMBY crowd. These are the people that vote in housing regulations, environmental review injunctions to prevent construction, etc. Regardless of whether UBI…
In the short term it would eat away at any income but it won't be 100% of it, and it will also vary by location. Some housing markets are more supply constrained than others.
Also a portable source of income would reduce demand for housing in cities too.
