If USA wants it, it can create millions of dollars with a very simple decision to make money.
You're off by several orders of magnitude, I think. The amount of "free money" that gets created is staggering, and there doesn't seem to be any end in sight--or a solution. The effects of quantitative easing combined with low interest rates have been great in the short term--the stock market certainly isn't complaining--but these economic crutches are going to break eventually.
Why wouldn't Argentina (or any other country for that matter) want to get in on the game? They see what the US has done and what results they've gotten. The problem is that the day of reckoning may well be something that their grand- or great-grandchildren are going to have to deal with. That isn't fair to future generations, but that isn't something politicians seem to care about.
You are right but the United States can get away with it because the dollar is the unofficial currency of the world, so other countries have no other option but to accept it or avoid the dollar but that will create issues with other countries that accept the dollar, also quantitative easing was nothing more but an attempt by the United States to weaken its own currency to try to boost their exports and other countries had no option but to weaken their currency as well so they could protect their economy.
