There is one more disagreement than you mentioned:
“All my current measure/amplitude would have to pay for the suspension process, but only a little bit of me would wake up. This means the real outcome of cryonics is [fraction of me that wakes up]*[awesomeness of immortality]-[disutility of paying], and this is negative.”
That said, I still want to sign up for cryonics. The problem is, convincing my relatives that many-worlds is true is about as difficult as convincing them that cryonics is a good bet by other means, or even that they’d enjoy living more than 80 years.
