You're exactly right and the economics of it are pretty well studied. I know quite a few people in real estate, they're always eager to upgrade their property (read: make it more valuable) because then they can make more money. If their price is capped, though, they just don't make the investment. Rightly so, but at the end of the day, the renter is the one getting ripped off by the politician he voted for because the rent was too damn high.

Just let people create value and trade.

PS: Sad that you're getting downvotes for a thoughtful, polite comment, too. Downvotes are for hiding idiocy and meanness, not viewpoints that you disagree with.
