Zoning laws ensure that property
It sounded in the first sentence like the city council wants property rights to be extensive (preserving them is the #1 goal). So if zoning laws are made to rein in property rights, then that sounds at odds with the first sentence, i.e. that's still our unexplained Paradox. If we interpret this answer to mean, "Yes, they want to protect property rights as a #1 goal, but they don't want them to become overly extensive, so they have zoning laws", that would work if the paradox had just been, "Given that #1 goal is property rights, why are the rights limited by zoning laws?" But the paradox is ... why are the rights almost nonexistent with current zoning laws? This answer is saying, "Well we need zoning laws so that there's not anarchy", but we need a way to explain why the zoning laws feel more like a North Korean autocracy.
