We need a VAC wave

Seriously, we need a VAC wave or VAC Tsunami, to be specific, because... well, everyone knows the reason. I really like casual mode, because I usually don't have time for full matchmaking match, so I prefer to play on casual, but currently it is infested with cheaters. Right now casual is more like Cheaters vs Cheaters, what seriously makes it unplayable. I know, we always had this problem, but since CS:GO developers read our complaints, I do hope, that they will read this message from community. Cheers, Mike. P.S.: English is not my native language, so, please, do excuse any of my mistakes.

EDIT: Thank you, guys for support, a lot of you suggested effective (maybe?) solutions:

u/imbavoe - What's the problem if Valve would buy some private cheats, inspect them and make countermeasures in VAC?

u/downvotenerd - The easiest prevention would to be TO NOT MAKE THE GAME 7 F****** DOLLARS.

u/KeeweePie - I know this would be impossible but having 'live admins' would be nice. Imagine you're in a MM and you think someone is cheating. You summon a valve admin to come watch live (no one knows but you so the suspected cheater doesn't toggle off etc), then based on evidence he kicks and bans right there and then and the game ties to make it fair.

Sorry for not getting through all replies and advices, I got classes until night. Will try my best to put all advices here.

EDIT2: Just edited format for easy reading. TIL formatting on reddit. Thank you for attention. Cheers, <3

EDIT3: I guess they are working on 64-bit scan?

u/Nyefo - Hey, there was a screenshot posted earlier that basically said that VAC can't detect 64-bit cheats. I don't know if this is true but it sort of makes sense. ;)

Here is the screenshot

Also, I have no idea why people keep downvoting this post, is banning cheaters bad or what?
