San Francisco is still a popular tourist destination. The sight of trashy homeless encampments and human waste in the streets negatively impacts tourism.
Newsom may be a lunatic leftist, but he still wants to keep the cash rolling in.
Even crime-ridden Washington, DC, keeps the tourist areas clean and safe.
Tourism wont save SF.
The big problem is the 250,000-300,000 daily commuters (workers and suburban shoppers, nighlife seekers, etc.) arent coming downtown anymore. That makes all downtown property (a Trillon worth?), worthless.
