I wonder if you have traveled to other parts of the world where there is "no zoning" and seen the reality of those places? I'm not talking about situations with some sort of theoretical Libertarian solution to tragedies of the commons but the reality on the ground. Zoning laws were a reaction to the situations arising from a state devoid of zoning. I assume and have confirmed in my opinion that they are a good solution to those problems, if not always implemented in an optimal fashion or twisted through the actions of special interests. You can of course claim that there are no problems arising from a lack of zoning and that the introduction of zoning laws is purely political in nature rather than functionally positive for society as a whole, but I'd like to see some real-world evidence rather than philosophy or assertions of opinion as fact.
