The sandboc euro plan

Euro is automated, meets sandbox conditions.

The binding force is the the Euro is thet nations the sell government products in the Euro, mainly government security and insurance.  The Euro is always the best measure of european coherency. Transaction costs zero.  There be no other restrictions on nations, currency or otherwise.  The Euro becomes automated street cash, everywhere.  Nations get to issue special currencies, bur they play a secondary role in commercial pricing, like food stamps or housing vouchers or penalties; as they wish. Sell these tokens for Euro, great business. We can do dual pricing in sandbox.
