I will quickly remark that some aspects of this comment seem to betray a non-info-theoretic point of view. From the perspective of someone like me, the key question for cryonics are "Do two functionally different start states (two different people) map onto theoretically indistinguishable molecular end states?" You are not an expert on the future possibilities of molecular nanotechnology and will not be asked to testify as such, but of course we all accept that arbitrarily great physical power cannot reconstruct a canister of ash because the cremation process maps many different possible starting people to widely overlapping possible canisters of ash. It is this question of many-to-one mapping alone on which we are interested in your expertise, and I would ask you to please presume for the sake of discussion that the end states of interest will be distinguished to molecular granularity (albeit obviously not to a finer position than thermal noise, let alone quantum uncertainty).

That said, I think we will all be interested if you can expand on

many aspects of synaptic strength and connectivity are irretrievably lost as soon as the synaptic membrane gets distorted

and whether you mean this in the customary sense of "it won't boot back up when you switch it on" or in the info-theoretic sense of "this process will map functionally different synapses to exactly similar molecular states, or a spread of such states, up to thermal noise". You are not being asked to overcome a burden of infinite proof either - heuristic argument is fine, we're not asking for particular proofs you can't possibly provide - we just want to make sure that what is being argued is the precise question we are interested in, that of many-to-one mappings onto molecular end states up to thermal noise.

EDIT: Oops, didn't realize this was an old comment.
