The difference is, murder is a crime. Money laundering is a "crime." 

Have you ever met a money laundering victim? Someone can be a victim of theft, but there are no victims of money laundering. 

Arresting someone for money laundering because they developed a private transaction tool is like arresting someone for "aiding and abetting murder" because they manufactured the steak knife a murderer used to cut his steak a week before he committed murder. 

Adopting the state's framing is losing the battle before a single shot has been fired. Money laundering is not a crime.  Crimes have victims. There are no victims of money laundering.
