Most people ignore that "do everything on the server" kills any game that needs fast interactions or decent local prediction, latency goes through the roof and you might as well play chess by email. There isn't a clean answer.

Kernel anti-cheat isn't an elegant solution either. It's another landmine, security holes, false positives, broken dev tools, and custody battles with Windows updates while pushing more logic server-side still means weeks of netcode tuning and a cascade of race conditions every time player ping spikes, so the idea that this folds to "better code disipline" is fantasy.
