I will be incredibly skeptical of any privacy respecting claims unless the design truly is cryptographically secure.

Also cash is robust. We are creating a situation where all economic activity becomes impossible if the network is down. With reliance on debit cards we're almost there already but this would remove cash as a fallback if it truly phased out physical cash. I'm not sure that is wise.
