Most implementations of rent control make it difficult to redevelop those properties into higher density housing. After all, if you could remove people from those units to redevelop, rent control wouldn't be worth much. This reduces total housing available which drives up prices elsewhere. Rent control is always a massive wealth transfer to a couple of winners from a massive number of losers.
