Of course it scales if you allow dedicated servers run by a 3rd party admin, like TF2 or Factorio or so many games of the past. But most companies these days don't want to give up that control.
That's just the thing, it scales very well if you're only running first party servers for a _paid_ game.
Escape From Tarkov had a big issue with cheaters because they would farm ingame currency, then sell it for real cash (Real Money Trading - RMT). This was literally a job for these people. Everytime they got banned, they just bought another account (~40$) and kept farming. If a support person bans one such person per two hours (at a generous 20$/hr Russian salary), the company literally makes money off of cheating.
I get why Free To Play games have cheater issues (even though for example Fortnite is raking in cash), but for pay to play games, I just don't get it.
