I think thats a current time issue that we have to deal with but on a long enough time frame the money will be chosen. In the 19th century you didn't have to diversify the money everyone was in consensus that it was gold

And silver and copper... at minimum
Those where scaling solutions
What do you mean?
People used silver and copper because they couldn't reasonably carry and pay with gold flakes of gold for coffee. The exchange rate was often price controled by the gov for example 15:1. When the gov removed those price controls the free market heavily preferred gold and it sucked up the liquidity from the economy.
