Come on now - the problems are at the margin, which is ever expanding given the literal exponential growth in the cost of housing over the last decade. There is upward pressure on every segment of the market and an infinite queue at the bottom. Not only are the marginally housed expanding in number, but the cost of solving the problem is too. I would advance the truism that homelessness is necessarily solved by putting people in homes. The cost of building housing for one in SF is several hundred thousand dollars. At 7k homeless, this problem would cost society a minimum of a few billion dollars just to definitionally fix the problem for the currently homeless. This is the same order of magnitude as the entire city budget - which, even if we wanted to, we couldn’t actually spend on housing because no one, including the government, can actually build stuff in SF. In so many words, homelessness is structurally intractable by any institutions without radically changing both California and SF laws around new construction. Hell, the city couldn’t even actually build bathrooms commensurate to the problem because once again, that would require building stuff.
