I understand what you are saying. There isn't really clear-cut guidance on this... and I think that this is what leaves it in a gray-area for a new technology (relatively new at least) and regulatory approach. We need clarity on it imo that favors individual choice and reasonable tax policy/regulation.

Unpopular opinion: Bitcoin is potentially being co-opted by the state

Yes, you are right that they are potentially doing their best to do that. "Potentially" is the operative word. Let us try to remember that it has been 15 years since the Bitcoin genesis block. This only meant that they are concocting plans for more than a decade to only come up with a flimsy KYC to co-opt Bitcoin. Coinjoin can potentially taint all of your wallets. But not all of your wallets. Also if that is true, if you think that the concept is true then you can always send your tainted coins to untainted wallets so that those wallets will be tainted as well.
