You are fully correct. The reason SF don't address it, IMO, is that it's a no win situation for them. If they clean up the homeless they'll be forced to make tough choices and enforce public order against people their stated ethos which tells them are oppressed and deserving of unlimited compassion. If they do the right thing and clean the place up there will be a backlash from activists. If they do nothing at all then they don't have to make tough choices, don't have to face backlash, and the frog continues to slowly boil which will be the next administrations problem.
