I think it is not about not trading persay - it's about not supporting a totalitarian mercantilist. While we both benefit on paper, the fact that so much of this wealth is concentrated at the top in America slows the velocity of money, and the fact that the Chinese are using it to fuel totalitarian measures compounds the trade deficit to the point where it is no longer simply about money and jobs.
Maybe having a gigantic trade deficit is natural and okay, but when it is being used to fund the CCP it is problematic. America may have to take a short term hit, but if it moves its factories out to India, Thailand, Taiwan, Mexico, even back to America the marginal loss in wealth due to trade will be outranked by the substantial benefit to society we will get from not fuelling a nation that seeks supremacy at the cost of humanity.
