This is 100% true, and while it does lead to some uncomfortable conversations, the smarter talking point is that even if the revealed preference rate comes out to be 60% or whatever, we’re building maybe 80-90% of our housing stock this way
While I’m making people mad by claiming consumers get what they want, a lot of consumers really do like big houses with no lot lines in the exurbs. Good urban form exists in lower quantities than demand for it but I think exurban housing has a very high demand and that’s why there’s so much of it.
