If there is one house, one person will still be homeless.

Ubi doesn't expand supply. You still have the same number of people fight for the house, you just bid up the price.

If there are 2 houses, the second guy no longer buys his vacation home for 500. This is actually what the situation is in the US. There are more houses than people, they’re just too expensive.

Or guy 1 and guy 2 both have 1000 more, so guy 1 still buys the second house, and the second guy uses Ubi to pay rent.
