Only proper NON KYC in my opinion is to buy Bitcoin directly for cash. Hand to hand. Otherwise you still leave a digital footprint in the banking system itself.
In Europe we use vexl.it from czech group Satoshi Labs. It works wonders. But I don’t know about community in US.
There are also a ton of Signal and Telegram groups in which you can arrange a meeting f2f (or should I say p2p).
