Having a mechanism to reduce growth is actually great.

It's hard to increase transportation infrastructure in a built-up area. And when you do, everybody says it didn't work because traffic is still bad or trains are still overfull. But they never notice that population increased during construction. If you could stop growth, then your transportation needs stabilize.

Doesn't really feel fair to me though, because it's so hard to move into the closed city.

Personally, I'm a fan of limiting rent increases to a max of something like 5-10% per year. Not so much that it's a total hardship to deal with a max increase; not so little that landlords have to do max increases every year or get way off market; also not so little that a landlord can't catch up later if they purposefully lag on increases to keep a preferred tenant.
