> 1. SF fixes the crime problem so its safe to be downtown. This requires many policy changes.
This won't work, because this is a meme. SF had an uptick in crime during the pandemic like most urban areas did, and it's slowly receding durnig the recovery as it is elsewhere. But a lot of people have decided, based largely on reporting in partisan news, that somehow this is a unique problem due to an out of control woke city government. And it's not. Here are some statistics showing the rates rise and fall:

Since you mention safety, maybe you want to look at violent crime stats only? This site of "most violent cities" looks credible, and points out correctly that SF doesn't even make the list. Oakland across the bay does, so maybe that counts.

But then Oakland sits well down the list, behind such wreched hives of scum and villainy as Indianapolis, Little Rock, and the Mos Eisley of North America: St Louis, Missouri.
Just stop, basically. It's just a meme. It's false, and it's leading people to some very weird conclusions (e.g. the "many policy changes" you're demanding to fix a problem that doesn't actually exist).
