“The overriding effect that the elimination of cash will have on people will be that they will lose their freedom of monetary movement. They will be subject to government and banking surveillance of every transaction and, increasingly, will be subject to legislation that limits currency movement. Once this point is reached, governments will be free to move to a stage in which they declare that money is not the possession of the individual or company. It’s the possession of the government and the government ‘allows’ the public to use its currency in order to conduct commerce. As such, individuals and companies had best ‘behave,’ or they might find the privilege taken away and the money confiscated.”
