> But one has to convince the residents or other voting population of that.
There's plenty of other things that that has obviously not been true for, I don't see why we should default to this extreme localism you seem to be advocating.
We didn't let local voters decide to continue imposing testing requirements to vote, we didn't let them allow businesses to continue to determine patrons based on race, we don't allow local jurisdictions to unilaterally confiscate land/property from private owners.
Given that this is a large problem, I don't see why non-local governmental action should be given an effective veto power by residents who don't want to see anyone new in their neighborhood. The burden is on you to justify that, given extensive evidence on how this would be welfare & growth enhancing.
> What the preference was aimed at is that many people want single homes, garages, yards, etc. If they can't get them, they will end up moving to where they can. If they have them, they (and the other neighbors) will advocate to keep the neighborhood that way.
Yes, plenty of people advocate for things that are in their self-interest yet bad for society. Your point?
> You can call something societally beneficial, but others might not see it the same way.
Sure. By beneficial, I mean net welfare enhancing for society. It's obviously not beneficial if your criteria is "increasing the price of my home by constricting supply."
