I actually heard a Chinese investor, active in the market, talking about how stupid the Canadian government is to allow him to do what he does. He was basically boasting that he will keep it going as long as he is allowed, and that the new regulations are weak and ineffective if you can afford a decent lawyer. In other words, "don't hate the player, hate the game."

Seattle will probably be too slow to react and end up in the same situation, but maybe it will get the attention of other cities/states before it becomes a problem.
