Things need to be maintained. Public HDB housing from the 1970s in Singapore is as good if not better than the new builds going up here in Germany. Destitution is not a moving goal post. You need adequate food, water, housing, healthcare, education and security. This is what UBI has to cover. If private housing is soaking it all up through rent seeking then it can be solved via rent controlled public or public/private (like Singapore’s hdb) housing schemes. You want more then you have to work for it.
