You are not making the point you think you are.

This is needlessly obtuse. The definition of the word is that it's non-constant. There isn't an ISO definition of the word no, but there are many reputable dictionaries out there that will serve as an alternative.

A lot of anticheat methods are not to catch the people with the proper, premium cheating software. It's to stop little Jimmy downloading an exe for Fortnite because he loses too much and making a new account as f2p is now the norm. As such, a lot goes into making it hard to have a cheat hide itself without significant effort from the user, be that running a custom kernel module yourself or some sort of emulation techniques. The kernel level anticheats can naturally be bypassed, but you have to do more than just running an exe most of the time which is about as far as the average kid who downloads their cheats from a YouTube video is capable of. The result is you catch 99.9% of what would be cheaters, and that's a much bigger improvement to your player base than catching the 4 players at the pro level who pay thousands a month for custom software which doesn't really matter in the grand scheme of things.
