You don't need thousands of dollars of hardware. You need one (1) Raspberry Pi 4, plus an HDMI capture card and a Raspberry Pi Zero to act as fake mouse/keyboard. You can totally do that for $50. (Probably less if you use an Arduino clone instead of a Raspberry Pi Zero.)
Heuristic software works against the most common cheats. Standard anti-piracy tricks work against the most common cheats. Kernel-level anticheat is only useful against a very specific kind of high-end cheat, and if you're going that far, you might as well use an undefeatable hardware cheat.
