The EU is not the Catholic Church, its a secular organzsation which a nation can apply to, it is by application, therefore consent, and its purely financial, foregoing the nation's right to print its own currency, it hands over that right to the European Central Bank. Currently the U.S. Dollar is the means by which one can buy or sell internationally, and that is without a nation's consent. We see recently where Greece is shackled with debt originating from New York bankers i.e. Goldman Sacks, operating with U.S. Dollar derivatives. Iceland faced a similar problem as have many European nations, there was no problem with the Euro, the problem orginated in America, with the U.S. Dollar.
