I might see eye to eye on a couple of your points. Gold isn't particularly useful as a metal. However, historically, it is desirable and has always been a solid base for many currencies. Silver is more plentiful than gold, desirable, and quite a bit cheaper. It has major industrial uses, including the new alternative energy market. For these reasons I'm more of a silver fan myself.
As far as our currency surviving and continuing too...it doesn't look promising to me. Take a pre-1964 dime for example (90% silver). You can almost buy a gallon of gasoline with it in todays market. The dollar has lost over 90% of its value over time. It depends on what your definition of 'survive' is.
Take the source with a grain of salt (the info in my head is from a book) but here's a rundown of failed fiats.

But when it comes down to it, I'm not an economist and I'm not certain I'm right.
As for the RP remark, I really look up to quite a few of his views. But not all. We've become a lazy consumer nation that produces absolutely nothing (for the most part). A big portion of our population feels entitled to the money others have worked hard for. Who knows whats driving our foreign policy but it's obviously necessary for our countries survival since we avidly pursue wars no matter which party is in office. We're rotting away from the inside.
I think we're gonna piss people off though haha, so I'll stick to dental related threads from here on out.
