>> The question is, -- is it a deliberate democratic outcome, or is it an accidental consequence of local zoning codes and city planning?
>> If governments are involved in planning, it's legitimate to use laws and the planning process to try and push these processes out of local minima towards more globally optimal outcome.
In a democracy, government planning is supposed to push the process towards local preferences. It's not supposed to "push these processes...towards more globally optimal outcome," which when decoded means "what you or what some distant technocrat prefers."
If the people disagree with you, then you're not talking about democracy, you're talking about "benevolent" authoritarianism ("we know what's good for you, and that's what you're going to get, like it or not").
Just be clear what you're really advocating for.
