However, in the situation being discussed, nothing survives.

Lots of things survive. They just don't happen to be part of the original body.

What you're saying, as far as I can tell, is that you care more about "preserving" a hypothetical future description of yourself (hypothetical because presumably nobody has scanned you yet) than you do about your own life.

Yes, I think given your understanding of those words, that's entirely correct. My life with that "description" deleted is not worth very much to me; the continued development of that "description" is worth a lot more.

These are very strange values to have - but I wish you luck!

Right back atcha.
