> Hoarding of property basically doesn't happen

This is very untrue. A lot of richer Chinese owners a bunch of apartments that they are holding for speculation, maybe they rent it out (and often not), but it’s still very much hoarding. You got a lot of sweetheart deals that happened 20+ years ago where many connected Chinese were able to acquire apartments, villas, and so on as opportunities.

Also, since the stock market is a hot mess, real estate acquisition was seen as the only real way to hold wealth in China.

> China considers housing to be a public right, which it is

You have more options for substandard housing in the cities (like sub basement room rentals aka “the ant tribe” in Beijing), but I also have no idea where you got this from. Rural hukou have the right to their land, but because they can’t sell it they can’t use it as collaterals in loans and such, making their life even harder.
