Some of your analogies strike me as quite strained:

(1) I wouldn't call the probability of being revived post near-future cryogenic freezing "non-trivial but far from certain", I would call it "vanishingly small, if not zero". If sick and dying and offered a surgery as likely to work as I think cryonics is, I might well reject it in favor of more conventional death-related activities.

(3) My past self has the same relation to me as a far-future simulation of my mind reconstructed from scans of my brain-sicle? Could be, but that's far from intuitive. Also, there's no reason to use "fear" to characterize the opposing view when "think" would work just as well.

(6) What Yvain said.
