Why don't banks print their own paper money / bank notes? 
There is absolutely no logical reason why each nation does not own and control banking and thus the supply of money.  Any system including the financial system works exactly the same way, regardless of ownership.  Banking depends solely on the confidence of the customers/investors. Therefore when a sovereign nation/state has ownership of the banks, the profits are kept in-house, within the nation, which is actually a bonus, and taxes can be off-set by profits, which is another benefit.  Any improvement or benefit by the private ownership of banking is a total myth.
