Ah, OK. You confused me by bringing up trist thinking they were Donald Trump, which seemed unrelated.

For my own part, I'm not sure why I should care about the nominal difference between two things with identical properties, regardless of how continuous their subjective experience is/has been, and regardless of whether one of them is me.

But I acknowledge that some people do care about that. And not just for subjective experience... some people care about the difference between an original artwork and a perfectly identical copy of it, for example, because the continuity of the original's existence is important to them, even though they don't posit the artwork has subjective experiences.

That's fine... people value what they value. For my own part, I don't value continuity in that sense very much at all.
