Why does the market price in one city need to be several times higher than in another? Why do so many of the high-paying tech jobs need to be concentrated on the west coast instead of more distributed? Are the benefits of that concentration truly higher, and truly purely rational "path of least suffering," in order to justify all the costs of it?

You also make an distinction between what consenting adults agree to in contracts and what those same consenting adults do in local governance and regulation. But why wouldn't they have the right to say "we don't want buildings over three stories here," say? Why is that necessarily "unreasonable" yet a landlord deciding to raise someone's rent 40% wouldn't be?
