Valorant does not have a cheating problem. The Battlefields and the CoDs of the world do. The difference between them is not that Valorant has a vote kick feature (it doesn't.)
The difference between them is that Valorant anti-cheat is far more capable, because it is far more invasive.

Depends on the incentives of the game and game price. Escape From Tarkov has a big cheating problem because people will pay for in game items, the devs will ban them, they will simply buy another copy of the game because they still make a profit even buying the game a few times a year.
I'm unsure how Valorant bans are useful, they must ban based on hardware 'signature' ?
The farmers will continue to find work-arounds if farming is profitable, but honestly, wtf is farming doing in an FPS - that's a bad design decision. Just let people play the game and enjoy stand alone sessions.

Cheaters will find a way - but not around ban-hammers... and if their cheating is so subtle that most people can't notice then it's a much less important issue to deal with (outside of professional league stuff - there sure, force people to do all sorts of crap to their computers if there is a cash prize on the line).
