Ugh, vulgar economic takes are so boring
We moved away from using metal as the universal equivalent because we needed to start making use of its material properties more within production. Additionally, we needed a more ideal currency that we could more directly control the inflation of, rather than having it be tied to metal production. Mertal was essentially just too risky to continue serving the exclusive purpose of money.
That said, fiat currencies are subject to the same pitfalls as metal currencies eventually. We're going to see this when consumer debt starts defaulting en masse.
