How is that evidenced by history except for some very isolated instances that lead to a fiat devaluation for very clear political reasons? It's like saying that all materialism on earth is doomed because it spoils. Sure if you give it a few 1000 years. No, the demise of fiat currencies is not predicated on history at all. You took a fair comparison completely out of context to try to make a point that is, however, not well evidenced by history.
One could say the same about fiat.
All fiat goes to zero, eventually.
