It was used to buy stuff from abroad. Now, selling the stuff to USA requires the seller to pay US tax on behalf of the American citizen to US government and then take that tax back from the American citizen. It is ridiculous. And also, if you are buying/selling low amounts and there is an intentional legal rule that says "small mounts are not taxed", then you are not avoiding anything nor using a loophole. You are legitimately buying a Canadian or Mexican item.
