Talking about households is no longer UBI. If you want to talk about UBI, give numbers per person and then tell yourself if that proposed number could allow a single person to live in the Bay Area without working.

You’ve conveniently made an arbitrary division of 2.6 to hide the fact that a doubling would be required if UBI were truly universal, allowed people to quit working, and didn’t place restrictions on household status (as you just did).
