I am not sure completely balanced trade works with the US dollar system. US exports dollars, other nations export goods for those dollars. It was a good deal for the US for decades. I don't think that is the case anymore. Maybe trade should settle in a neutral reserve asset like gold or bitcoin. Bitcoin is a better option but it will be argued that it is too volatile to settle global trade. But if it was to settle global trade every nation would need to have a bitcoin reserve and it likely would be 10x the size and not as volatile.
