Likewise, blackmail. People imagine envelopes with incriminating pictures. But that kind of blackmail rarely gets used, because once you've given in to it, then what? The blackmail will still hang over your head. You'll serve the blackmailer for life. At that point the victim may think they have little to lose. (Relevant regarding Donald Trump. He has far too much ego to serve someone else for life, even if there was some "Moscow tape").
Instead, the blackmail that's powerful is the one that the victim knows will cost the blackmailer a lot to use. The understanding that if I go down, you all go down with me, is a lot more useful to make us come to an agreement. That's probably how Epstein got away with things for so long.
Well, that's reassuring.
