Of course, you can find all kind of opinions, but it seems to me, that the EU (more specifically the Euroarea) could be just a loose commercial and travel area without a common currency or a real federation with economics stabilizer between regions and a real democratic mandate. What it can't be is something in the middle, like it's now.
