Thats bs, non-kyc sats is forward looking opsec. Protect yourself from the state and malicious people knowing how rich you are and reveal parts of your stack when necessary buying a car for example. Also there is not enough Bitcoin in the world for people and institutions to be fussy about history of corn. Bitcoin is #Bitcoin.
Another way to look at is what you do when you kyc. You leave all your details together with your adress and how much Bitcoin you have in hands of exchange. Every, every single exchange leaks your docs at some points, could be in past or the future. When Bitcoin is worth millions your kyc data is going to be most sought data on internet. And while you can tell the state about your boating accident and it may work… Its not going to work against criminals they are going to get every last sat they have next to individual’s name one way or another.
Hey bro! What’s your social security number?
