How much control on cash by the Government is tolerable? What will happen if all currency is withdrawn, with electronic bank accounts and transfers the only option, and interest rates are turned negative by the powers to be (and with all cash withdrawn, no one is able to withdraw all of their money from the bank - thus, forced to tolerate negative interest rates)?
Who is to monitor and control the excesses of the Government over citizen's daily lives and livelyhoods, including the right to earn an honest living? Is over governance possible?
These, and many such questions, are argued in this excellent book with some mind opening and thought provoking discussion. Highly recommended.
