I see a lot of possible root causes being mentioned, e.g., blind bidding, zoning, foreign buyers, corporate buyers, and the vested interests of existing home owners.

Here's two more: income inequality, and the construction skills crisis.

Income inequality: You might think "prices are crazy, no one can afford this", but the fact is that some people are affording it, even repeatedly. Depending on your family and circle of friends, you may know someone who owns 2, 3 or 4 homes or one over-sized home. It is not uncommon, just not usually discussed openly. They buy or retain homes and then rent them rather than selling. Why horde houses? Some people just like to see a tangible asset. Most upper middle class people have most of their assets in stocks. But with stocks up significantly in 2020 and 2021, a lot of people are ready to diversify into real estate. And those who own homes can watch them appreciate even if the home sits empty.

Construction skills crisis: At least in the US, there just aren't enough construction workers to fill construction jobs. You could open up zoning rules, but that won't make housing starts instantly increase, because there are not enough workers. A generation of people has been taught that knowledge worker jobs are the best. I think that is a largely correct. Even with construction salaries up, I think that it is tough to have a long career doing physical labor in the trades.
