That's...that's terrible. That it would feel worse to have a chance of resurrection than to have closure. It sounds depressingly plausible that that's people's true rejection, but I hope it's not.
Religion doesn't have the same problem, and in my experience it's because of the certainty. People believe themselves to be absolutely certain in their belief in the afterlife. So there's no closure problem, because they simply know that they'll see the person again. If you could convince people that cryonics would definitely result in them being resurrected together with their loved ones, then I'd expect this particular problem to go away.

That would depend on how high the chance of resurrection is. Closure is relatively certain.
