I don't see what's privileged about continuity. All of us are pretty different in the evening from in the morning. And in theory you could have been created at noon with a memory of the morning. You might not even exist yet.

Not that I'm saying those are particularly useful possibilities to be aware of. To the contrary, my point is that the self, despite being a fiction, is generally too useful to see past.
