But anti-cheat software is not doing this? You are free to do whatever you want on your computer as long as it doesn't interfere with the game process. Most, if not all, anti-cheats will also not do anything when the game isn't open.
Some games (including Rust) give you the choice to play with no anti-cheat, too. You'll only be able to play on servers that allow players to join with no anti-cheat but you are not blocked from the game.
I would be more worried about computing becoming more phone-centric where Apple and Google are in control of what you can and cannot do.
