I agree with you the issue is scale, but the scale when it worked was when gaming was niche. You can't put that back into the bottle.

The history of plenty of anticheats start with community servers, not matchmaking. Even Team Fortress Classic had enough of a cheating issue that community members developed Punkbuster, which went on to get integrated into Quake 3 Arena. A lot of 3rd party anticheats were developed in that era for community servers. BattlEye for BattleField games. EasyAntiCheat for Counter-Strike. I even remember Starcraft Brood War's 3rd party ICCUP server with 'antihack'.

You still see this today with additional anticheats on community server solutions. GTA V's modded FiveM servers had anticheats before it was added to the official game. CS2 Face-IT and ESEA servers have additional anticheats as people do not think VAC is effective enough.
