Quoting, "the whole point of crypto was to break the pyramid scheme of central bank planning and currency, yet here we are using it as a meta-pyramid scheme." and immediate following question: "There’s a sense crypto has lost its way, but it also seems like our best hope of beating the current exploitative and extractive system." In both there are unproven or unsubstantiated claims here. We're all vaguely aware banks lend fractions of deposits on the calculated risk that demand on those deposits never exceeds deposits. So what's the sense in which this is a pyramid scheme? And in what sense is central banking extractive? Presumably the implied criticism is bank bailouts, and federal government's perpetual deficit spending as in the USA?
