As long as you believe that any theory of subjective experience will ultimately be physicalist, this argument doesn't really work.

There is no continuity of subjective experience even within the same brain, you can be deeply unconscious for extended periods of time and come back.

Yeah, you can argue the same thing about going to sleep, there's no guarantee that the same "you" wakes up.

From the outside, an "identical clone" is indistinguishable.

On the inside, the clone feels exactly how you would feel.

The only problem is the "I don't want my 'me' to die" feeling.

I bet most people would be fine with death/rebirth teleportation.
