Even though I 100% agree with you, the one piece of merit here is that the world is pissed shows that they recognize they lost something. They would not care if we were merely shooting ourselves.

Now if they are pissed and totally lost trust then we are totally fucked. But if they are pissed and willing to negotiate then maybe something can be salvaged out of this. It would be nice to have 20th century hong kong esque zero duty free trade between the US, EU, Mercosur, Canada, and all the other friendly nations as a result of us all learning how dumb this is. But I won't hold my breath.
