I sometimes wonder how the hell people cannot see the difference here: the drachma, the lira, the deutsche mark, simply do not exist today. Hence, no one can unpeg them from the euro or the dollar. Let me put it another way: Argentina devalued its own currency; Greece will have to introduce another one. The new currency will not be the drachma of the 1990s. It will just have the same name as the drachma.
