"....There is no evidence of this - zero. The Weimar hyperinflation didn't end paper currencies just demonstrating that you can debase fiat currency as much as you want but there is no better alternative...."

While it's true that hyperinflationary events haven't caused the demise of paper currencies, there certainly were alternatives used during those times - trading in commodities in black market situations. The only way people can survive during those times is to trade and barter basic commodities, foodstuffs and other essentials. Cigarrettes were the real currency of some European countries after the second world war. Those who had excess food (mostly farmers) also accepted gold and other valuable commodities as payment. When things get tough paper currencies are exactly that - paper.
