Unless there are an equal number of housing units to office seats in a particular region of a city, by the pigeonhole principle, it's not possible for everyone to just live where they work. Also working spouses and other cohabitants can't always just work in exactly the same place.

Your suggestion works for exactly one type of person, who has enough resources to outbid others for housing and either lives alone or has a non-working spouse.
