I'll edit the post to make it clearer what analogy I intended. The question I meant to raise is that if someone has an Alice-like position with respect to cryonics, where they don't intuitively identify with their resurrected future self, does a cryonics evangelist have an argument against them?

I'm absolutely not trying to show that it's wrong to sign up for cryonics. I'm raising a possible way it might not be wrong not to.
