That is a single example. Where do you think seized Bitcoin at government auction comes from? Why is there no government auctions for Monero? Do they have any? I guess we would never know "just like tor's 3 hops..." Except that any future mistakes can potentially de-anonymize you. Trading partners can see your balances and trace you. Not only that, but over time any future mistakes from others that participated in your coinjoin rounds reduces your "privacy" and is out of your control. Made evident by people like this paying for a tiny mistake made years later. You don't seem to understand the problem. Almost no user is going to do all these little optional hoop jumping tricks, spend way more money, and waste time to "wash" their coins. The best Bitcoin "privacy"-wizard opsec-gymnast has worse privacy than the most retarded Monero user pressing send. And that is a shame.
