Except there's still competition. If renting becomes $200/wk more expensive, then sharing a room, or living with family, or move out of the area (to somewhere that still has BI but less constrained housing) becomes $200/wk more appealing and that'll make the difference for some people. Rents would probably rise, but not the full $200.
