I have learned not to value local control. This is because I value incumbent residents and future residents equally, but local control only can give the former group of people a voice. In this way, I do absolutely find it anti-democratic.

I would definitely prefer issues like marijuana and sanctuary to be settled on the national level if that were possible. Same goes for zoning. I don't see the paradox you seem to see; when these things are forced to be solved on the local level, I'll support my position. That doesn't stop me from thinking that sometimes the local level is part of the problem.
