I’ll bracket this by saying I’m not very technical so I could be wrong… But I assume that any days I’ve bought through kyc entities, which is most of them, can be easily tracked to me. Unless I mix them I don’t think there’s a way to solve that problem. The average person who bought bitcoin on an exchange probably doesn’t self custody and almost certainly doesn’t know what mixing is.
Beyond that, the state could make it very difficult on bitcoiners. If they drastically limited to banned Bitcoin purchases on exchanges it would really set back average adoption. Or if they made it difficult to off ramp bitcoin into cash by raising taxes or making you report all transactions on your taxes (this may already be required I guess - I don’t know because I never sell 😂). I can barely get my friends and family to think about bitcoin as it is right now. Some policy like that would make that worse.
I think things like Drivechain, where we could build a privacy sidechain for example, fedimint, which is more private as I understand it, and a circular bitcoin economy, which would allow people to avoid off ramping into cash, will all help with this.
So I guess I’m my humble opinion it’s not a completely unreasonable concern.
