Zoning is one of those topics where people from all walks of life display cognitive dissonance.
People will come up with a justification for violating their own set of beliefs or principles. It's true of liberals, conservatives, libertarians, and every other type of person.
Principles like the following get cast aside:
📜 reducing poverty / increasing housing affordability for lower-income people
📜 social integration / reducing segregation by income or race
📜 climate action / reducing sprawl, vehicle miles traveled, and per-capita emissions
📜 economic mobility / removing barriers that lock people out of high-opportunity areas
📜 treating housing as a basic need rather than a protected asset class
📜 free markets / allowing supply and demand to set prices and quantities
📜 limited government / rejecting local micromanagement of land use
📜 individual liberty / letting owners decide what to build on their own land
📜 fiscal conservatism / avoiding the higher infrastructure and service costs of low-density sprawl
