Even making that comparison suggests that there is a situation in which cryptocurrency is effectively and widely used as currency side by side with fiat. I don’t see that ever happening. I don’t think governments can (or should!) give up that much control over the financial system. And this argument actually reaches back to prove itself: since crypto will always be used for speculation and not fill a useful role in transactions, all the energy used is effectively wasted!
