See the core issue is that you get US dollars in exchange, which is of infinite supply but still happens to have value due to the reserve currency status. You send your stuff to US, you get the dollars and pay your suppliers etc but they don’t send that dollar to US to get something they want because US doesn’t actually produce that many stuff. So you should be able to augment the US, pay the producers with your imaginary dollars you put in the books for example. Sure that will be fraud but it is fraud only because you are not US. However that’s not the point, the point is that you don’t actually need US, you need to figure out a financial instrument that fulfills the role of US and that must be possible.
