I think I read the same article (Portland?). The key thing is that the change was slow because demand was building up slowly. OTOH, if changes are held back for decades and demand is pent up (ie soaring prices and increasing commutes) then there's going to be a surge once changes are allowed. ie SF will see a far bigger, faster change than other places. It's precisely the places that have a huge pent up demand for housing that have the biggest problem with Airbnb.
