I think there are some situations where you can achieve that payout in real life, but admittedly by “literal prisoners dilemma” I was referring more to the fact that the mafiosi are literally held prisoner and induced to snitch on each other. And that introducing an extra negative payout for snitching is both the literal and the game-theoretic solution to the dilemma.
