This is an absolutely horrible argument, housing (namely multifamily housing) doesn't apply the same rules of economies of scale that other consumer durables do both due to natural capital costs and the inability to prefabricate huge parts of the building process (You cannot prefab the giant ditch you need to fill with concrete down to the bedrock that takes 100s of thousands of man hours to build). The only viable solution to reduce the cost of housing is prefabricated, but moderately sized apartments/multi-family homes. The way you get this is not by unilaterally removing regulation, but by getting rid of local regulation in favor of national regulation.
