You are right, I misread. I apologize. Unfortunately, you don't get to decide who replies to you or not, and the "but fiat currency!" is even easier to disabuse

You are right, I misread. I apologize. Unfortunately, you don't get to decide who replies to you or not, and the "but fiat currency!" is even easier to disabuse: it has societally inherent worth because it can be used to pay taxes even if it is not accepted in any other venue (which of course it is), whereas cryptocurrency's primary use is to grift or be grifted. That is inherent worth, unless you intend to go full big-brain about the Fall of Society, and at that point nobody is going to care about your digital ledger unless it comes with lead-backed securities.
