you answered your own question. when you trade your bitcoin out for Monero, someone else has received your bitcoin and its their problem. did you just frame that person, or are the other people following the bitcoin transactions between addresses just wasting their time. do those people even know that one of the series of transactions they've been following for years was a trade for Monero? no, they don't. this reality is indistinguishable between legal and illegal transactions. for anyone passing by: the scenarios so far are based on starting with bitcoin, briefly swapping to monero, and ending with clean bitcoin. many people start with Monero, and only get the amount of clean bitcoin they need when necessary to pay for things, which completely alters the problems and solutions.
