I am more or less with Keynes because a demurrage ( demi-urge?) currency would distract with all that arbitrage. The general debt problem is that there must be sufficient growth to eclipse the debt over time. This is the only way that it can work. If increases in the money supply are not sufficient to enable/support an increase in GDP, then that's rather a Catch-22. This depends on one hairy bit of psychology - either create value, you value-creators or we'll have inflation. No slacking, as they can now do. It does not help that QE{I,II,III} were "we are increasing the money supply, but we are not really increasing the money supply."
