First up you’re comparing two completely different scales of bad things happening. If someone cheats in a game it doesn’t really meaningfully affect anyone, having your house broken into is a direct threat on your property. Locking a door has minimal downsides but allowing someone who can be trusted less than most corporations to have root access to your entire computer has a pile of risks and opens doors for worse. If anticheat is just to deter cheating then there’s no justification to have more access. If you can’t handle maybe having a match ruined then you shouldn’t be playing online games.
