Nocal, if you don't believe we have a dollar crisis right now...
It's not the paper that is the problem, it's that the fed increases the supply exponetially on a daily basis. We create massive inflation all the time, and the ONLY thing keeping the dollar from being dumped and REALLY becoming valueless is the fact that Oil and gold are priced (and bought) in dollars. If that were to change overnight, and Oil were to be priced in Euros, every central bank that holds dollars in reserve would dump them and then the US Government will be broke.
Sound money isn't such a horrible idea when you actually understand the effects of our monetary policy.
