its like saying game piracy is bad because you can get hack in your pc

if your pc is so important then maybe don't install these particular software

its all about trade off

I don't install games that require kernel level anticheat. I wish those games would stop using them because without that I'd play a few of them.

Kernel level anticheat isn't a silver bullet, either. It just simplifies the work of the anticheat programmers. I personally think that the silver bullet is behavioral anticheat and information throttling (don't send the player information about other players that he can't see/hear)
