The response you're responding to here was to "ben_w", he discussed better-than-a-billionaire housing. My original reply to your earlier comment is above, basically just asking what type of housing you anticipate under a UBI system.

To me, "just enough to avoid starving" is a prison-like model, just without locked doors. But multiple residents of a very basic "cell", a communal food hall, maybe a small library and modest outdoors area. But most of the time when people talk about UBI, they describe the recipients living in much nicer housing than that.
