Problem is that 3^^^3 payoff is a part of specific miracle hypothesis.
Prior probability of magic needs to be chosen so that you'll be able
to move it up to near-1 if it actually happens. As 3^^^3 payoff will
take really long time to verify, you are allowed to be equally
doubtful about the property of this specific magic to deliver this
payoff, and so you can set equally low prior probability on it.
