You seem to have a low opinion of people's ability to make their own decisions or to decide what's in their own best interests. No, we must have properly appointed government bureaucrats make all decisions. If we deny someone's property rights, tough. They should know better than to disagree with their intellectual superiors in government. Just keep paying those property taxes and shut up. /sarcasm

Seriously, would dumping dioxine increase or decrease someone's property value? One would think it would lower the value, so why would people rush to make their property toxic waste dumps?

As for dairy farms in the middle of towns, it seems unlikely that someone could afford enough property to operate a profitable farm in town. Land prices in most towns are just too high, especially given the low profit margins of most farms. Now, if the farm was already there and the town grew up around it, then the people who move next door really don't have much grounds for complaint about the smell (although the bonehead still will). It's like the idiots who move next to an airport then complain about the airplane noise. Sorry, but I have no sympathy for them.

And what's wrong with a car wash next door to a school? Are schools supposed to be surrounded with an economic free zone, and if so, for what distance?
