Rent control doesn't make existing apartments get beamed up onto the Starship Enterprise, and supply of housing isn't primarily constrained by it. It's constrained by a lot of other things, and maybe when those other barriers are removed, and a bunch of houses get built, it might start being constrained by this one. But that's not where we are today.

I imply that the market is imbalanced because someone not having a place to live for a month is homeless, while a landlord not having a tenant for a month is a multi-millionaire who is out a few thousand bucks.

This wouldn't matter in markets with reasonable vacancy rates, but in markets with unhealthily-low vacancy rates, tenants have to eat whatever shit that trickles down to them, because they can't go somewhere else.

This should all be obvious to anyone who rents.

> Sure, but price controls don't solve this.

Not directly, no, but cost of switching (for both tenant and landlord) is a reason for why rental markets are quite weird, compared to commodity ones.
