Much of that displacement was internal to San Francisco, and the movement of a constant number of homeless people from one area to another can still be net positive, if the area displaced from is denser and more economically productive. External areas would respond in kind. However, they will balance two possible responses: "anti-displacement" and provision of homeless services, depending on what's most effective. The latter does more than shuffle people around. In fact, that dynamic in reverse is how we got to the status quo: other areas have essentially no homeless services but plenty of appetite for displacing to places that do have homeless services, like SF.
