It doesn't have to be significant. Just having 1 hacker in the 100 PLAYERS PER LOBBY will ruin the game - there will be no chance of a legitimate player winning, ever.

Games have been abandoned even though companies actively catch cheaters because no one wants to play against someone with an unfair advantage. If Epic releases a game where they literally cannot catch cheaters, that game will be abandoned in a week.

Your defense of cheating is laughable. People are trying to play a game with a closed set of rules. Saying that your hacks are legal because they're turing-complete is completely nonsensical. You are not playing the same game that people signed up for. You're hijacking someone else's enjoyment for your own power fantasies.
