Well, that's just silly. Hook up a Raspberry Pi as your keyboard, mouse input and video output and all the anti-cheat fails. Same (largely) for VMs, same for many emulators.
And if nothing works you can always build a robot pushing mouse, buttons, etc.
Of course you can raise the bar, but if anything has been shown it's that cheating is not something that anyone has been able to prevent yet.
In many situations you can also interfere on the packet level. Of course maybe you need to extract some key, but in many situations that's not exactly hard. And then you can hook something into network.
The cheating isn’t just about input speed or accuracy though. It’s about seeing around corners or having knowledge about other things in the game that you can’t see on the screen.
