So... is there some way to have both the benefits of multiple currencies and a single one? The convenience of a single currency in terms of cash is becoming less relevant as cash itself is used less, but my understanding is that the main theoretical benefit is that it strengthens the single market. Basically allows EU companies to have suppliers and customers in any EU state, without having to incur currency risks. How great is that benefit? Could some of it be achieved while allowing individual EU members to control their own monetary policy? Or on the other side, could the Euro be kept, but the negative effects somehow mitigated, perhaps via changes to transfer payments, maybe based on the difference between what would be the domestic currency value and the Euro?
