It's an illusion even in a dualist model, because dualism does not logically rule out copying. The illusion, to spell it out further, is that I am a unique entity persisting through time. That is what I feel
to be "personal identity" at the visceral level, and even though
intellectually I know better, I can't shake the feeling.

It's stubborn, even if an illusion, eh? If you were duplicated, would you
be
prepared to kill your duplicate? Who would you kill?

If it came to a fight over the last place in a lifeboat I might be
prepared to kill my duplicate and he would be prepared to kill me (I
can say this since I know how he thinks). I would feel bad about
killing him because he can then anticipate no future experiences:
there will be no future entity that remembers being him so the
illusion of being a person persisting through time would end. I would not worry about destructive copying of myself or someone else because then the illusion would persist. This is a rough answer and it is not
difficult to think of situations that cause problems. For example,
taking a drug such as midazolam which causes amnesia could be seen as
equivalent to killing your copy.

Wouldn't it be easier just to commit suicide? You are still killing the same
person on your account.
If I commit suicide the illusion of persisting through time is
destroyed. If I kill my copy or if I enter a destructive duplicator
the illusion is maintained.

So the illusion really is important, then. If you commit suicide, you do continue through time because your duplicate survives. Or is that different?

Yes, for idealist, and magician, the illusions are important. "illusion" does not mean that we have to dismiss them. Sometimes I use "dream", or "hallucination", but those word have also dismissive connotation. With computationalism, we can say that the only non- illusion are 0, s(0), s(s(0) ... and our consciousness of this, and elementary relations between: all the rest is an "illusion". It is the same as the way Einstein conceived time, an illusion, but a persistent one. With comp, primitive matter, and primitive consciousness does not exist, but of course, matter and consciousness exist and play a key and most fundamental role.
