Rentals are almost 40% or the market so it will have a real effect. Of course this requires more changes to our systems. But given the terrible status of current US social structure, anything you do worth doing will likely fail without a number of changes to support it. There is nothing that makes 700 sq ft something you can't own and can only rent. That's a condo. People will still buy and sell depending on their life goals and situations. If you move, you will be more likely to sell rather than hold your old house for a rental. Refis will still exist, along with the pressures they create for some people to sell, etc.
