The last page of Sonia Hirt’s book Zoned in the USA lays out a key paradox in the American zoning system:

Isn’t it ironic that American residential space is so sacredly residential (so protected from intrusion through land-use law, that is) only because it is so commercial (because it is an object of trade rather than an object of our sentiments)?

Perhaps this another piece of evidence that single-family homes are one of the biggest objects of American consumption as well as key pieces in the American economic system.
