Not OP, but personally, I subscribe to a different economic theory: by engaging a scammer I am diverting their resources towards me and away from someone else.
It’s not a perfect rationale and I see what you mean but, for me, it would be like confronting a thug on the street when one has good reason to believe they are victimizing someone else out of sight. Would I lose more by confronting them than they stand to gain, or should I just confront them no matter what?
