But they aren't talking about a "free platinum" policy, where you could take your ounce in, get it minted into a million dollar coin, like in the "free silver" days. They are saying they can take one specific ounce of platinum and decree it to be a trillion, by stamping on some writing. Your catalytic converter's value would be unchanged.
It's just debt free "fiat" money. only it's 99.99999% fiat and .000001% metal.
You'll notice that even now we did not return to free coinage of gold and silver ~
There's another possibility here ~ the guys advancing this notion have heard some information from very classified sources suggesting that some LENR experiment using platinum really paid off, and the stuff really is worth the big bucks ~ they just don't know why. Rest assured if there's another exceedingly valuable use for platinum it's market value will climb to meet the nominal value
