The virtual currency battle between Facebook and Zynga reminds us that:

a. Once a company starts a virtual currency, it is difficult and costly to abolish the currency. For nations, the same is true. Countries, like Greece, that entered the European Monetary Union now find it very difficult and costly to abandon the euro. b. Companies that start virtual currencies can abolish them rather quickly, which stands in stark contrast to countries, like Greece, that entered the European Monetary Union but now find it difficult and costly to abandon the euro. c. Companies that start virtual currencies are like countries, such as Greece, that entered the European Monetary Union.

This stands in stark contrast to companies that start virtual currencies and wish to abolish them.
