But mixing Bitcoin does not equal money laundering and the mere activity of going into a business and making your money trail more private? That can't ever be a crime. Otherwise our regular use of fiat is wrong.
It is even understandable that you don't want anyone else to know with whom you are doing business or with whom you are in touch. If you see a doctor and it would be possible to pay with Bitcoin on day, nobody wants that to be stored in the blockchain available for anyone to see and identify you. Even if you just buy a pack of cigarettes or alcohol, there is no point why anyone should be able to fully identify and analyze your behavior.
Exactly. Privacy and seeking privacy are not crimes. Criminal activity is always criminal activity. People need to stop confusing both as the same thing.
If I am doing a crime, what I do to hide it cannot be also automatically a crime. Wearing a face mask to hide my identity while in a bank could be a crime (to prevent making robbing a bank easier), I agree, but you cannot outlaw wearing face masks.
The problem with mixing though is that there is no other way for it so it can compromise with authorities, for me I wouldn't risk letting mixers loose knowing that they can be used for crimes like money laundering or tax evasions. Think of it like this, there is a bowl of with 100 M&Ms and around 20 of them are poisonous and will kill you instantly, no way to tell if they are poisonous, I am sure that no one is going to risk taking it unless they are suicidal or have a death wish.
I really can't see the link here. Your Ms are always poisonous, but mixing is not always poisonous. As I said in my example above, if mixing is always poisonous (to use your bad example), then your use of fiat is always poisonous (dollar bills and cocaine, for example).
