Ok but what if I said: we shouldn't arrest cartel hitmen, because that would just make some other murderer take their place. The game-theoretic choice seems to be to keep doing what they are doing, while allocating some of that dirty money towards research in nonviolent conflict management?

Believe it or not, law enforcement agencies actually do that, more or less every day, in every country. There is value in having crime organised, predictable, somewhat circumscribed, and controlled by people you can communicate with and influence to a degree.

Real life is rarely binary.
