Is there really anyone who would sign up for cryonics except that they are worried that their future revived self wouldn’t be made of the same atoms and thus would not be them? The case for cryonics (a case that persuades me) should be simpler than this.
I think that’s just a point in the larger argument that whatever the “consciousness we experience” is, it’s at sufficiently high level that it does survive massive changes at at quantum level over the course of a single night’s sleep. If worry about something as seemingly disastrous as having all the molecules in your body replaced with identical twins can be shown to be unfounded, then worrying about the effects of being frozen for a few decades on your consciousness should seem to be similarly unfounded.
