It might work someday, maybe. But it won't work now. The corpsicles which currently exist are just as dead as if they were cremated. I understand, sort of, the psychology of people who lie to themselves about this, but that's all that's happening.
You don't know that because you don't know the physical limits of reanimation technology. In 2014, a human brain was vitrified with no ice crystallization or fracturing for the first time. Certainly, the first viable preservation will occur (if it has not already occurred) long before the first reanimation, and eventually discovering that we began to preserve people too soon would be much better than discovering that we began not soon enough. Even the primitively frozen might be retrievable centuries from now.
You don't know what future technological capability will be. Current Alcor and CI patients are preserved well enough that their bodies and brains could in theory be repaired by technology at the physical limits of possibility. The information is there.
You are saying that existing technology is unable to fix the issues of vitrification. That is correct, but irrelevant.
