Hard to really judge the hand. not sure of the blind lvls, effective stack size or even what the texture of the flop was. certainly more risky of a play with the button cold calling the LooseAgg 3bet. Not sure what the button was thinking in calling the 3bet but then folding to the small 4 bet when he is getting way batter odds and closes the action pre. but yes, I would agree your opponent would likely put you on a very narrow range.
