Yes, I agree, as do the quotes and Agar even: because this is not Pascal's wager where the infinites render the probabilities irrelevant, we ultimately need to fill in specific probabilities before we can decide that destructive uploading is a bad idea, and this is where Agar goes terribly wrong - he presents poor arguments that the probabilities will be low enough to make it an obviously bad idea. But I don't think this point is relevant to this conversation thread.
