I also suspect that a lot of them don't understand that Grexit would mean a Greek default on her external creditors, which mostly are the other nations of the Eurozone. Some might consider this, but then dismiss it as they do not really care the most about recovering the funds lent to Greece anyway, or perversely consider the funds already lost in all but name due to the unsustainability of the Greek debt pile.

There are huge loss of face issues. The deathcar has overpowered the drivers, and now to admit would reveal not only how the very architecture of the Euro is flawed, but also that their venomous characterisation of the Greeks was a cover for their own cupidity. It has become institutionalised cruelty no less.
