The building industry never really recovered after 2008 because the only surviving companies were extremely cautious. In order to get more builders, there needs to be more places to build, and entry into the industry needs to be easier. It's all permitting, zoning, and discretionary processes stopping housing from being built where it's wanted to be built.
Well I've shared a statistical analysis and raw data series backing my points and directly contradicting yours. On the flip side I guess we have "trust me bro."
To the extent "it's all [any individual cause]", that cause is rising incomes. The second major cause of rising housing prices is cost of inputs (labor, land, material). Zoning definitely plays a role, but again: there's just no evidence that "solving zoning" will actually solve affordability. We should do it anyway because it'll solve all sorts of other problems in our built environment, but there's not good evidence affordability is one of them.
