Gold Standard, Silver Standard, Oil Standard, or Pokemon standard, having your money depend on a supply of stuff is pointless until the entire rest of the world does the same. Further, what happens when you discover a huge cache of Gold? Is all the currency
suddenly worth less? or more?
The underlying bargain of currency is labor and so when countries are willing to trade their labor for less, they sell more of that labor. Westernized economies act like they are removed from this process because we get paid by managing the labor of others,
but ultimately the world runs on labor.
I propose a new world monetary standard called the "kilocalorie"
