hope this doesn't cross the line on political stuff, but I've got two words fer ya: Regional Zoning.
You can use zoning laws to ban without banning anything you want. In my home state it's illegal to operate a strip club within a certain distance of a church, and guess where new churches keep popping up(seems to me that in the case of such a law the facility that was there FIRST should get the right-of-way, but what can you do?).
I've read over and over of persons with the (overly broad) label of Sex Offender being forced out of their homes because so many laws were passed saying "you may not linger, reside, ets within X distance of Y(ZABCDEFGHIJKLMNOPQRSTUVWZ) location" that when all was said and done there wasn't any place left where they COULD live.
