There are huge consequences to the common denominator in most transactions going up and down, but you don't dodge them by not having a central bank. There are economists out there who hate the idea of having a central bank control everything--they tend to argue for rule-targeting central banks. Examples include the inflation+unemployment target (the Taylor rule) or rules based on the circulating quantity of money (NGDP targeting). So some people think there are ways to have a currency that is simultaneously economically good and manipulation-proof.
