It’s like saying seatbelts are useless because some people still get hurt, so instead of seatbelts we need a lot more ambulances and hospitals.
Like any complex system, games have a funnel. These technical measures reduce (but not to zero) the number of cheaters. Then moderation can be more effective operating against a smaller population with a lower percentage of abuse.
Alternatively, it's like saying poisoning your customers is a bad way to reduce complaints, because some of them survive. Matter of perspective.
Isn't this the argument used against non-kernel-level anticheat and server-side anticheat in the first place ?
On the other hand, all the games / servers I've seen which are successful against cheater have some very good moderation.
Look at Counterstrike with regular VAC based matchmaking and then with kernel level anti cheat in FACEIT. One is overrun with cheaters and one isn't. It's the same game.
Those technical shenanigans clearly aren't working, be ready to be disappointed if you thought that a TPM would help against cheaters. Cheaters always find a way, what those game needs is proper moderation.
Yes that does cost money but that's the only known thing that works in the long run.
