I can think of pretty much no cases where you would _need_ to convert your money to cryptocurrency, then conceal where it came from using a mixer, and then use it for something legal.
Why would you need a mixer? If you want to hide it from your friends just send it to a new address and then buy with that address. Who can prove that new address is yours?
Also if your friends then regularly snoop and trace every single one of your transactions so they can laugh at you for your purchases, I wouldn't consider those to be your friends.
I mean fair enough, you have contrived a legal example. Yes, I admit it does have valid use cases, I just don't think they're very common at all.
