For the whole bloody state of California, where I'ved lived all of my life. Of which the last 37 years has been in a single-family residence in a single-family zoned subdivision that I designed myself. There is lots of buildable land here. Draw a straight line between Sacramento and Fresno, find a point halfway between those two cities and there I am.
There are lots of areas where this solution is necessary, and probably some other whole states.
I never faulted a NIMBY mentality from people tied to 360 months of mortgage payments; nobody will buy a house if they think their area will be targeted for Gibsmedat Relocation. No reason to destroy peoples’ nest eggs with this nonsense; it is basically breaching contracts with them.
