While I agree with you to a large degree, from my limited perspective there is one problem with server side cheating detection, such detection would be inherently reactive (eg. it will take few cheating actions, before it is detected by service side anti-cheat) versus on client anti-cheat that is deliberate (eg. cheats can be detected before game is initialized, potentially)
