I'm skeptical for all of the opposite reasons: I don't trust civilization (extraction society), but I wonder how many are only skeptical because of investigative reporting like Zeke Faux's "Number Go Up". Your response isn't bad. The recent US regime repaint does make it less likely that the Fed will jump in to protect "legal tender", but the chance is not zero (see history of local currencies). Almost nothing is. Use cases are scrambled right now, so we'll see who becomes the arbiter of the paradigm (hopefully soon). Someone will try an AI hub (problemmatic reliability), then a government hub (China?, UK?), but the bottom line will be convenience: Farmers' Market transactions. PayPal. Venmo. Dollars during climate catastrophes. Maybe crypto will be as solid as a phone dropped in the mud and run over by a tractor. Time and failures will tell.
