While it is not realistic to eliminate all cheaters, what I will say is that cheaters can easily ruin a game, especially one that has lasting consequences such as, for example, Tarkov. Which I did end up stopping playing due to cheaters.

In addition, if you start seriously questioning whether you lost due to the other person's skill or their cheats after every engagement, then it erodes the game's foundation and things start falling apart. You can't do the process of analyzing what you did wrong or could do better, because you might have done the right thing and just lost due to a cheater. You can't be confident that you could have gotten good enough to win that engagement next time, because it might just be a cheater and be impossible. Strategy goes out the window because you cannot assume that the other person acted rationally in a non-cheaty context. It subverts the rules of the game that you agreed to. Like when you're playing chess and the other player keeps knocking over your queen with their finger. It simply stops being fun. The game turns into something else
