I think the biggest issue is the rapidity of introduction, and secondarily, the 'on/off' nature of it. I'm sure it's been said to death, but stable means time to adapt and not random. Picture Trump sitting in his office. A concerned, confused look is on his face. Clearly his mind is dwelling on an issue, a problem. After a while, he picks up the phone and dials a number. The phone connects and a person wearing a headset, at a call centre answers. "Support!", they say, "How may I help you?" Trump replies "Hi. My tariffs aren't working. Can you tell me what's wrong?" Support answers "Have you tried turning them off and on again?" Makes as much sense as anything.
