I agree with you. I just recently read the excellent 2015 book by John and Jonathan Theodore, “Cyprus and the Financial Crisis: The Controversial Bailout and What it Means for the Eurozone”. These British academics said the same thing, that Greece would have been better off to leave the euro and default on its debts. With the kind of currency devaluation the use of the euro made impossible its economy could have recovered rapidly. In good time, Greece could have re-entered the euro. It seems to be one of those cases where what seemed to be cautious and prudent policies were really cruel and irresponsible. The book also makes clear how shabbily the troika treated the Cypriot people, under the pretext that the only people being hurt by the unprecedented bail-in of Cypriot banks were Russian oligarchs.
