This is only a sample.  The NSA has all the communications meta data.

A digital monetary system can be structured to essentially operate as the communication system.

Single medium of exchange: digital units.
Single door through which all communications/transactions pass
Transaction identification associating exchange to individual entities.
Date/time/location information.
Total information capture and retention ability.
Single authorized legal capture authority under government control.

Our security depends as much on the security of our monetary system and its protection.
