That's the pedestrian view of blackmail. What if there's a form of blackmail that is more powerful than that. After all, "For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms." You'd be a fool to think Q is only speaking metaphorically here. So expand your thinking. Satanists worship satan for a reason. And it seems that could extend to a supernatural form of blackmail too.
