The displacement of artists and musicians is, frankly, ruining San Francisco. It doesn't have to go on. The city can stop it. San Francisco already forbids developers from turning housing into offices. Residential hotels can't be turned into tourist hotels.
Historic landmarks have special protection.
There's no reason why cultural and performance space can't be added to the list. It would ban developers from changing such spaces into offices, condominiums, or commercial or retail outlets. The supervisors should call for immediate hearings on the issue, with the goal of creating a model law that would preserve what's left of cultural space in the city.
