The true opportunity cost of toxicity

We all know that toxicity creates negative experiences for other players and makes the game a worse experience. But a real cost of toxicity is that it negatively impacts the games quality. Instead of creating new features, balancing the game, or otherwise working on other aspects to make the game better some of the effort and money must be dedicated towards detecting toxicity and punishing toxic players. We may never know about the other nice things the well-mannered fans could have if people weren't jerks to each other. I'm really surprised nobody brought this up.
