I live in SF, where there are a variety of shops. The ones I walk by all seem clean, orderly, and well run. Certainly more so than some liquor stores I can think of. So I'm happy to have them as neighbors. That said, I understand why other cities would have been more reluctant to license. Not everybody needs or wants to be a pioneer.
If we're still having the same problems 5 years out, I'll be more concerned. But personally, I'm a big fan of subsidiarity, the principle that decisions should be made as low down in the power structure as possible. [1] That different people are deciding differently right now is how we'll learn the best ways to do it. There's no urgent problem here that requires a centralized solution.
