Shrug. If two million people want to live in a city which has room only for a million, something has to give. Rent control doesn't increase housing. You must either increase housing somehow, or leave a million people unhappy. If you don't mind the other million, and only care about people already living in the city, you can make it honest by introducing a city-wide Tenant Permit issued only to current tenants. Rents stabilize due to fixed demand, people aren't tied to one apartment, and landlords are incentivized to offer better service. It has all the benefits of your plan and none of the drawbacks, right?
