I wholeheartedly disagree. More toilets won't fix the problem -- I suspect they could even potentially worsen the issue by making the city a more attractive place for the beyond-hope.

Fixing the mental heath system that Reagan dismantled would be a far better approach, and a persistent camera + facial recognition system could allow for more effective identification of those that would benefit from commitment.

The ACLU, psychiatrists, and other reformers are more culpable than Reagan. Deinstitutionalization started long before 1980. See, e.g.,

  https://www.nytimes.com/1984/10/30/science/how-release-of-mental-patients-began.html

Some amount of reform was needed, but the deinstitutionalization that occurred was too extreme, too rapid, and lacked adequate backstops. Politicians were just doing what they were told by lawyers and psychiatrists, and they were eager to comply because it meant huge cuts in spending.

So you are saying anyone who can't afford the insane price of having a house with a toilet in SF is mentally ill?

If they remain in SF, yes. Departure is a reasonable option.

San Francisco's policy is basically to leave the gushing wounds alone, and instead think hopeful thoughts about how we really should be eradicating all disease.

True, that would be the real solution, and then we wouldn't need those pesky bandages. No pathogens in the air, no risk of infection. Leaving wounds open also helps bystanders feel the problem, and probably motivates some to go into medical research or to work harder at it.

But "visible infections will motivate the end of disease" is a batshit insane public health program, and "car break-ins will motivate the end of capitalism" works about as well as an anti-poverty strategy.
