So, then, what does this poorly named "safe harbor" get you? You're basically putting together your own noose to hang yourself. If they want to try to figure out every BTC purchase I've made, that's on them. They can. Almost all my sats are KYCd out the wazzoo. They ain't getting my stack. Take my Fiat. Lock me up. I'll face bodily harm over this. I might crack eventually, but I'm not making it easy.

Well not really because we are born with the noose around our neck and this is one of the myriad things we have to do to prevent them from pulling the dead drop lever. We may outlast the gallows but for now we stand upon it. The goal here is to ensure that if you sell int he future and report capital gains you can have a record of the basis from which you are calculating it that's accurate and satisfactory. On the other hand, if the idea is to simply not comply with the law then you're right there's no point in keeping sound records, Im just saying I dont recommend it because if you aren't in jail you can do productive stuff instead.
