Don't think so, I believe it will always be controlled, no matter what the world currency/petro-dollar ends up being. At least that's what I've heard from some folks... Time will tell, though. For the short-term, owning PMs is a good idea. In the very long run, nothing will have value except for whatever the one world 'currency' ends up being. As it says in the Bible, "they'll throw their gold & silver on the ground cuz it's worthless" (I'm highly paraphrasing there).
The only thing i'll throw on the ground is spent brass.
