Here’s an exercise. Go to Wikipedia for “Money Laundering” -> “Notable cases” and sum the amounts laundered by all famous banks for the last 10 or 5 years.
Then try to say again that “crypto is for money laundering” with a straight face.
It's a terrible argument though. If I ran a bank that literally only did money laundering, and I applied your logic, it wouldn't matter because, hey, others have done it more in aggregate.
Even then it's like, if I killed someone, I could say, well Americans in general have killed X many people, so I'm certainly less kill-y than Americans.
