Why not take your Euros and buy GBP or USD? I don't understand how currency controls work. Is the assumption that if Greece, say, goes off the Euro, then "New Drachmas" will have a fixed "official" exchange rate that disadvantages anyone who moved their assets abroad prior to the shift?
It will be the opposite. People with money in Greek banks will get new Drachmas at some official exchange rate. Most likely (100% likely, in fact), people who have money in foreign denominations will do better. The whole point of going back to a sovereign currency is to inflate away national debt.
