I argue it is not, because unreasonable desire shouldn't be part of "housing" conversations.
If every single person wanted a detached house on Robson Street, that's clearly just stupid and should be ignored.
You're right that it's stupid, but that's what the laws attempt to do! It Is literally illegal to replace single-family houses with denser housing in the vast majority of Toronto, Vancouver, etc. That means everybody who doesn't fit in those houses is physically displaced to the exurbs, never mind that the increasing demand with no accompanying increase in supply makes prices skyrocket.
I don't care about your nonsensical attempt to redefine what words mean; that's objectively a shortage!
Shortages are what restrictive zoning laws are designed to do, and they are working exactly as intended. If you don't like that outcome, the only sane thing to do is abolish them.
