Dunno. How would the gold conversion work?
Gold, beyond a few industrial application, has value only in the mind. Its pretty and its rare but it has almost no utility.
That’s why I was thinking a commodity should be used instead.
In the old days, walk in with an ounce of gold, walk out with $20. Walk in with $20, walk out with an ounce of gold.
Who is going to accept 20 different commodities (or store the commodities to exchange for the $20) when you want to get your $20?
Sounds a little clunky.
