Let me get this straight, though: you would rather that CoD, Fortnite, LoL, Lichess, etc. just make it open season; no anti-cheat. You believe that as a gamer, your gaming experience would be enhanced if there was no anti-cheat.
If that's your logical conclusion -- that no anti-cheat is the answer because there are always going to be some cheaters -- then I have nothing. We'll just have to agree to disagree. As a gamer, I'm happy to install anti-cheat if it can defeat the majority of casual cheaters -- even if it costs some frames or adds overhead to the startup time.
