This is a good point and it would definitely make me upset if it happened to me. Hopefully you'd have some say in the matter or be grandfathered in. In this particular case Then man has been illegal for all these years and someone final called him on it. At least that's my understanding. And they didn't just say you're out of here they told him follow the zones and he didn't.What if your property was "re-zoned" after you purchased it? I don't know if this could happen, but it seems to me if all your neighbors were in favor of re-zoning you couldn''t do much to stop it. Would your property be grandfathered as is, or would you have to conform to the new zoning?
