Nothing?? What are you talking about? Go look up how much tax money the SF government spends trying to help the unhoused in their current budget. But no amount will fix the problem because if you ask a drug addict if they want help (and it’s not help getting drugs) they usually say “no thanks.” Many addicts are never ready to accept that kind of help. Sadly.
No amount of help will solve a housing problem in a city where people can't afford to live. Build more housing.
