Lots of towns have already done this. Berkeley did it years ago. It doesn't matter at all. The fact that Berkeley bans certain land uses means that the town next door, Emeryville, falls prey to fiscalization and simply makes their whole urban strategy be making money off of encouraging all the things Berkeley bans. The effect is that there are probably more gas stations than Emeryville than there would otherwise be in both Emeryville and Berkeley. The same goes for big box stores which Berkeley also banned. Emeryville is just a long endless chain of box stores and gas stations right next to Berkeley.
