You Know didn't predict this, he simply reported it as one of the signs that the Global Financial System was about to collapse.
The article linked to says among other things:
At the root of the crisis is a recession triggered by years of public overspending and heavy borrowing that has left Argentina on the brink of defaulting on its staggering $132 billion public debt.
I agree with You Know that debt is basically fake money and that that fake money is piled on top of fiat money which is also fake money since it is only worth what people believe it is worth. Paper dollars are not "worth" anything other than kindling or toilet paper. You Know also argues that derivatives take it a step further and create yet a third layer of fake value. I can't discount his arguments. At some point, something actually has to have a real value of some kind to be worthy of trade for something of real value (ie. a house, food, clothing, metal, services rendered, etc.)
The bottom line to survival is the earth's ecosphere and its limited natural resources. We are clearly straining these. In the end they are the only thing of value. As one exasperated Argentinian in the linked article exclaimed: "We are hungry, we have to eat!". Yup, that's the bottom line. You can't eat dollars or pesos or yen.
