What I never hear mentioned is the elimination of national currencies and currencies in general. The metals producers should get together and coin "money" for circulation denominated in the WEIGHT of metal. A gold coin could be struck with 100 stamped into its face denoting 100 grams, for example.

Prices of everything would be set as G:S:C so a typical car would cost 945:50:0 meaning 945 grams of gold, 50 grams of silver and no grams of copper. The units could actually be whatever could be agreed upon. No one would care if the gold was minted in the US, Russia, or on mars.

This would eliminate currency arbitrage, exchange rates, central banks and would mean that government is out of the "money" business. Price inflation would be a market force, not the whim of some banking cabal. Deficit spending with central banks monetizing the debt would be impossible. Wars would be less likely as now they need to be paid for in cash G:S:C, not thin air "currency".

Credit card companies could store all the metal an individual or company owns and we can all use plastic as a convenience with the option to withdraw any part of OUR metal any time we want. No more fractional reserve banking.
