If you want to ever convert your money from BTC to a fiat currency, how so? Don't all the big exchanges require rigorous id verification? Sure you can store your BTC in a wallet making it pseudo anonymous in the sense that everyone can see your transaction flow but no one can link the wallet back to you. But then where and what can you actually use it for.
You can atomic swap BTC to XMR to obscure where the coins came from but you would have to then launder them to get fiat. I'm not sure how that's done, buying gift cards could be part of it. I think in many cases the coins are just funnelled to a jurisdiction that doesn't have KYC.
Chainalysis frequently hints that they have visibility into monero.
