That's close but not quite right. I understand exactly how necessary cars are for most people, having spent many years trapped in a car-dependent life myself, and I am so glad to have escaped from it that I want to do everything I can to liberate others. A walkable urban life should not be an expensive luxury - there is no fundamental economic reason for it. The scarcity is entirely a function of policy, primarily restrictive zoning codes, and we can fix that.
