This is just to record my thoughts, so I can look back on this and see what I got right and what I got wrong. Or at least, what I changed my mind about.
The Euro was a mistake. I hoped (and still hope) to see the Euro dissolved. But the Euro is now stronger than before. With enemies like Syriza, the Euro does not need friends. The government of Greece made a bad situation (that was maybe slowly improving a little) worse. And it will get much worse in the future, regardless of the vote in the referendum. If this is what an exit from the Euro looks like, who would want to follow Greece in exiting the Euro? And the perceived willingness of the ECB to do open market operations was probably what nullified the Greek threat to destroy the Euro unless it got what it wanted.
