Meanwhile, I think the move is motivated by 1) actual interests of people in his cabinet and advisory group (notably Bannon), and 2) populist pandering for re-election. I think that's sufficient motivation. I think the ham-fisted implementation of the policy is either arrogance meeting incompetence or an attempt to anchor expectations so low that Republican elected officials can later happily get on board with him when he's merely being very awful instead of incomprehensibly awful, saying he's "learned". I hope it's the former.
