&gt; In a free rental market, you would see some current SF residents leave because they&#x27;re not willing to pay market rates, but the market rate would drop as a result. In other words, long time residents would move out to make space for the people who want to move in and are willing to pay for the privilege.<p>I don&#x27;t get why there&#x27;s so much agreement here that that&#x27;s the desirable outcome.  Allowing people to be quickly, dynamically uprooted out of their homes as price volatility swings up and down in different areas -- that has a lot of real human (read: economic) costs associated with it that are not obviously to account for.  For example, the difficulty that children will face by being uprooted from their schools and friendships.<p>Obviously the cost-benefit of any particular program requires very careful analysis, but I think there&#x27;s quite some value in the idea of stabilizing rent to allow people agility to make the appropriate life changes that correspond with changing housing.
