Isn't the real problem here that German banks own a lot of Euro denominated debt issued by the broke EU states like Greece, Italy, etc... if all the not broke states leave that leaves Germany alone to either bail out the broke states or bail out their banks when the debt goes bad? Britain though they are part of the EU has never been a part of the Euro.
