To be able to use P2P, all must KYC, this is to prevent money laundering and trade fraud.
That's not accurate at all. There are a number of peer to peer platforms which not only don't collect KYC, but don't even have a mechanism in which they could collect KYC even if they wanted to since there are no accounts or registration required. Check out Bisq or RoboSats for example, or others available here:

Further, there is no evidence that KYC is effective at preventing money laundering. KYC is about surveillance and control, nothing else.
As for buying bitcoins on Kucoin exchange, I don't think it is too bad since they do not force you to do KYC
Until you trigger one of their unknown algorithms and they lock your account and demand KYC.
If am wrong pls you can list atleast one exchange which you can use their P2P without submitting kyc.
Bisq, RoboSats, LocalCryptos, HodlHodl, LocalMonero, AgoraDesk. More here:
https://kycnot.me/There's nothing really wrong with KYC
Apart from the complete lack of privacy. And the risk of your details being hacked/stolen/leaked/sold. And the risk of identity theft literally ruining your life. No, nothing wrong at all.
