And what if an expelled Greece insists in using the euro?

Sir, Ralph Atkins discusses that the “Fear of a Greek exit could strengthen Draghi’shand” September 6. 

Again the possibility that Greece defaults, the others get mad and expel Greece from the eurozone, but Greece keeps on using the euro, is not discussed. Why? To me that sounds as the most reasonable proposition, so that Greece does also not lose what it has left marketing a hard to sell neo-drachmas. 

And why is so little discussed about making the best out of all those funds held by Greeks outside Greece? Is it that it would have been preferably that those funds had been lost too?
