Eh, I'll give you part of Pascal's Wager. The other part of it is the logical absurdity of thinking that someone who doesn't already believe can be blackmailed into believing. Pascal's Wager can only be used to defend belief, not create. (But every time I've heard someone IRL use it they seem to not understand that). That's a big part of what Pascal's Wager "is" to me.
I think that argument applies to cryonics. :) The people who invoke the wager are trying to defend their belief, not actually convert others. To anyone who doesn't believe in cryonics, the wager is pretty absurd.
