I LOVE how you portray this as a positive thing when it's really the start of where all the fraud began.  People started to deposit gold into facilities with people having last names like "Goldman", "Goldberg", "Goldstein", and they would give them paper certificates representing that value.  They realized not everyone tried to withdraw all of their gold at once, so they started lending fractional reserve, and so began the fraud of the millennium.

Massive amounts of lobbying, coercion, military force, etc, was then used to maintain this fraud.  People did not just "choose" to be scammed for perpetual eternity.

If it fails the Occam's Razor test for a currency, IT'S A SCAM.  You don't need a magician behind the curtain setting variable interest rates at a whim and all this other jibberish you're talking about.
