You don't need to ask this question when you can readily observe a century of economic data on rent control. People do all kinds of acrobatics to avoid giving up their rent controlled apartments.

Why wouldn't they? They are locked in at a price that was frozen in time and can't increase. And there is a thriving black market for re-leased rent-controlled apartments. (black markets always occur when supply is artificially restricted).

You're posing a hypothetical that only happens in an alternate universe where the foundational ideas of economics and human behavior don't apply.

Ok so 2/3rds of the way through your case you've already moved the goalposts. Here's a reality check for you: a dwelling is a dwelling, whether it is rented or owned. Rent control always and everywhere produces a shortage of dwellings. This hurts everyone.

Lower rent cannot be legislated any more than waterfront mansions for everyone can be legislated. It would be wonderful, if true. But it is not.
