In the US, at least, the government has been slow to acknowledge the root of the housing crisis. While simpler designs do build faster, the main impediment is municipal-level zoning controls that prevent the construction of denser housing. These codes often insist on non-brutalism, insomuch as they mandate certain materials, setbacks from the lot line, and other aesthetic intangibles, but their main purpose is to appease residents (voters) who generally wish to impede more people from moving to whee they currently live.
