It never struck me as a good idea. The advantages with regards to travel/work seemed like something all Europeans should be able to enjoy without 'membership' in some artificial community.
I'm sure the nuances of it all arent apparent to me but from what I can pick up, there is a real sense that its smothering nations with a regulatory framework that virtually no one actually benefits from, beyond failed states struggling with austerity.
I'm sure things will get a little awkward once it's officially dismantled, either via a Le Pen victory in May or through organic and apparently inevitable means shortly thereafter, but is it really something Euros would miss if the travel/work benefits were somehow maintained?
