The problem is the "rent seeking" the use of politics to artificially constrict supply to create market inefficiencies. This is a basic concept in Microeconomics. As I mentioned elsewhere in this thread, economists such as Paul Krugman, Edward Glaeser, Tim Harford, and many others who are "domain experts" make this statement. I find it interesting how people listen to aircraft designers, nuclear power plant designers, civil engineers about buildings and bridges, but ignore economists who basically all agree about the market inefficiencies caused by zoning codes that artificially create scarcity and constrict housing supply thus driving up housing prices. Remove the market inefficiency and the cost of housing will drop. This is independent of Google, Facebook, foreigners buying homes, etc.
