Could that happen? Sure.
But SF Board of Supervisors have SO MANY REALLY BAD PROBLEMS they need to be solving.
Instead they are choosing to be pro-active legislating against tech (because they hate tech, let's admit it). Pro-active legislation is something that should be higher level -- state senate, federal, etc. Local politicians should be listening to their constituents to determine their priorities.
They need to get off their butts and solve our homelessness problem with the $50k per homeless individual they now have in their yearly budget. Why do I still see crap all over the streets? Why do I feel like I'm going to be attacked when I'm in the streets?
Some guy stabbed himself with a knife right buy the Caltrain station last year. If that was an isolated event, I wouldn't have a problem.
Their priorities are so out of whack.
