Extremes are unhelpful, we must find balance. Institutional ownership restrictions reduces monopoly pricing power, and rent controls de-risk against rents rising faster than wages. Outright outlawing of institutional ownership is not a solution, but allowing it to operate in a highly regulated fashion (where there are still some, but more reasonable, returns and mobility is enabled for mobile consumers of this service). If the argument is continue increasing supply vs rent price controls, well, it is clear that isn't happening in the short term.
TLDR Housing needs to be pushed more towards being a regulated utility, vs a free for all. If we regulate electricity like a utility, why not housing?
