I now think the purpose of the ECB article was to promote Bitcoin development in the Europe region, so that it's not so US-centric. I'm sure that from their point of view, one risk with Bitcoin is that if it gets popular, whichever country holds the most will gain massive profits from seigniorage (i.e.: the fruits of speculating that "cheap coins" that cost <$50 to make will get sold for $millions, making the Yanks unfairly rich the same way that their Dollar exports stole wealth from the 3rd world to fund "The American Dream (TM)".)
