Didn't read past these first two sentences as it is pretty much clear that they don't know what they are talking about. In simple terms, the author of that piece, whoever he might be, is putting the cart before the horse. It may in fact look like paper money leads to a collapse of almost every economy but in reality it is always the other way round. Whatever case you consider, the failure of paper money is the outcome of the failure of the state, not its cause. The Weimar Republic, Yugoslavia, Soviet Union, Zimbabwe, you name it, it was all a failure or breakdown of the state which quickly led to a collapse of the monetary system.
I might have to re-read that article, but the relationship between the state and its money seems more of a chick-and-egg (in both directions) than a horse-and-cart case.
Confidence in state money depends on confidence in its state, true. But confidence in the state also depends on confidence in its money. The British Empire (and the Dutch and Spanish before it) were brought down by the incentives for the elites to issue too much paper money (even though this 'money' was technically debt payable in gold or silver.) Savers and investors moved money to the rising US after World War I, and Britain lost the empire and endured economic pain over decades of the 20th century. (The war was only the last straw that broke the camel's back -- since Britain had only 3% of the gold required to redeem its total issue of paper sterling under an official gold standard, we have to view paper sterling as a bubble that was simply not possible to sustain long-term, with or without a war.)
The French Revolution issued the Assignot, and the American Revolution issued the Continental, both of which collapsed due to their paper nature, not to the failure of the revolutionary governments. Even Weimar Germany held together well after the hyperinflation. With a new land-backed currency, the money system and the state were back in health in a few months.
I would agree that in many cases, failing states and/or bad policies lead to hyperinflation and collapse of the currency. But these aren't the only examples of paper money. The most recently strongest paper money is the dollar. Yet its purchasing power today is on the order of 1% of what it was at the founding of the Federal Reserve in 1913. If it has 'not collapsed' yet, it is because of bubble dynamics alone.
As we have seen with the Spanish, Dutch, British, and now American money bubbles, state supported bubbles might last a long time (and maybe much longer than outfits like ZeroHedge predict!) but the nature of bubbles is to burst -- no exceptions.
