Wouldn't the labor force's production be fiat currencies' Proof of Work? At the moment, cryptos are an asset, and any item a seller accepts as a fair exchange is a currency, but money isn't valuable, and supply and demand impact inflation. No one, not even Milton Friedman, can mathematically prove the quantity theory of money leads to inflation, and the jokes on us for believing austerity is better than investing in the public.
Our entire economic system is a fabrication. Finite resources and the environment are the only genuine value, but we overlook these because assigning worth to worthless materials confuses us. If people stopped using fiat currencies, they'd use something else, and if people stopped believing in inauthentic worth, true value would emerge.
Governments support/allow cryptos because protecting capital is their role. The media loves creating us versus them and we love taking a side, but it's odd. The more crypto haters, the more crypto investors defend their investment, but why does anyone care if you invest in crypto?
Also, I assumed the bankers facilitated the creation of crypto in 2008, but I guess we'll never know.
