I agree it's unlikely, at least a full pull-out of the market is basically never going to happen. But if they were to get a somewhat high tax I'd expect their lower-profiting stores may end up getting closed down because they're not worth keeping open (IE. They're basically making nothing off of them after tax, but they could sell them off and then open a store somewhere else that may now be profitable since the US costs more to have stores).
