Giving the rich a monopoly on a fixed tier 1 subset of real estate in a market with huge demand is not how you solve affordable housing to the "local" middle class. It will create synthetic incentives, and escalate prices on all real estate as demand seeps over into black or grey markets. Changes like these need to be across the board, or not happen at all.

This isn't "giving the rich a monopoly", it is restricting their existing monopoly by declaring a type of housing (newly constructed sfhs) out of their reach.

But the middle class of today will be the rich of tomorrow, and not allowing them to rent out their own homes when they move means that basically they are prevented access to the same mechanisms of wealth creation that made today's rich people rich.
