You are not following the argument. You said that you accept the possibility of knowing the outcome from purely theoretical (indirect) argument (that is, not the kind of data where you are presented with successful revival of anything), as in the Einstein’s anecdote. I ask what kind of indirect data/argument that would be, that is enough to convince you to sign up. That you may do that for signaling reasons is irrelevant to the question.
