Martin Armstrong summarizes the headway being made to ban cash,  and argues that the goal of those pushing a cashless society is to prevent bank runs … and increase their control:

The central banks are … planning drastic restrictions on cash itself. They see moving to electronic money will first eliminate the underground economy, but secondly, they believe it will even prevent a banking crisis. This idea of eliminating cash was first floated as the normal trial balloon to see how the people take it. It was first launched by Kenneth Rogoff of Harvard University and Willem Buiter, the chief economist at Citigroup. Their claims have been widely hailed and their papers are now the foundation for the new age of Economic Totalitarianism that confronts us. Rogoff and Buiter have laid the ground work for the end of much of our freedom and will one day will be considered the new Marx with hindsight. They sit in their lofty offices but do not have real world practical experience beyond theory.
