That's exactly the same as the arguments made by proponents of the gold standard, and it's just as wrong now as it was then. Crypto is an alternative to investing in gold, not an alternative currency. It has all the same market dynamics.
Crypto is far too broad a term to use and say it's the same as Gold.
In many ways it worse (PoW for Bitcoin), in some its better (banking for the bankless). However you can have Crypto that has an inflationary mechanism that's codified (can still be gamed), none the less it can be inline with modern monetary schemes.
