And how would you implement that?
So basically there needs to be a government agency which tracks the inflation adjusted price of your home. Ok that's easy. But this agency now also must have the power to prohibit you from selling your home for any price other than their official inflation-adjusted price. If they don't have this power, then someone could offer you more for your home and thus you made a profit, and your goal fails.
Would you expect to have voter support for such a price fixing scheme from any side of the aisle? Would you even want to live in such a world?
I keep asking because often these threads go into something like "Oh you just stop making homes an investment and problem solved.", but that word "just" is moving some pretty big mountains there. If you drill down on what that really might mean, it never comes out to something realistic to implement.

Demand does not go down. Your scheme just favors owners living in their home as opposed to corporations buying them to rent them out (which I fully and enthusiastically support!). But actual number of homes and actual number of families wanting to live in them didn't change, so demand didn't change.
