Funny how most of us love to talk about how terrible pet store's are and that people shouldn't buy animals at them, and only from good breeders. But then throw a fit when the city of SF agrees with that!
I live just across the bridge from SF, so I've been keeping tabs on this a bit. They aren't trying to ban owning animals. Anyone that is coming to that conclusion obviously isn't reading much into this. Lolo is right; the restrictions in SF are already pretty tight. Not much will actually change. Honestly, the only problem I have with this is that it will put some pet store owners out of business. But most in sf these days make all their money from pet supplies and don't really sell any live animals except a some fish and a few rodents and such. So yeah, this won't really affect a whole lot, and most likely people won't even notice.
