It's a game. I don't like the idea of forcing economy so early, but this move was perfectly fine. The hat could, I repeat, COULD make a reappearance. So it's up to you if you want to trade for it or not. Let Amy and the staff do what they wish with the game. It was abundantly clear to me that one of the 2000 hats would be pulled right early, as they were hard to get early. Don't let one hat bother you. There is plenty more to come.
Personally I have no care for this hat. It isn't that special to me.
