Terrorism is state funded and preventing laundering won't do much.
Laundering helps people in countries like Mexico, where a large part of the tax revenue goes into the hands of few. Why fund a state that is run by gangsters?
Well traffic law has similar catch-all like 'disorderly conduct' laws: 'careless driving'. Up to the officer's discretion, basically.
I'd also note that encryption is "not be something that harms anyone" but "often done to conceal actions ... harm".
This particular money laundering debate is very unlike the encryption debate. Actually, you could argue that money laundering is a very specific type of encryption, you're just encrypting the source of your income by adding noise instead of encrypting digital data.
Let's see just some of the reasons you'd use encryption:
So bad people can't find your passwords
So bad people can't get into your bank account
So bad people can't see what websites you've been visiting
So bad people can't see your pictures
So bad people can't steal your intellectual property
And why would you need this type of privacy?
So criminals and bad people can't injure you using your private information
So corrupt governments can't see what information you've been reading/writing/sharing
So you can have some assurance that your email/social media/etc accounts are fully controlled by you, and likewise for those you're interacting with
Now let's see some of the reasons you'd launder money:
So the government can't see where you got the money.
That's it.
And why would you need this type of privacy?
So the government doesn't know you committed a crime to get that money.
That's it.
People don't launder money because they're ashamed to admit they work at Microsoft. People don't launder money to hide their employer from criminals who want to hurt them. People don't launder money to hide it from other citizens. People don't launder money from legitimate businesses. People launder money so the government doesn't know that they got the money illegally. That's it.
There's a lot of legitimate reasons to encrypt various things, and no one has ever argued that encryption is only ever used for legal and good purposes. The argument is that while encryption is sometimes used for crimes, the good things it enables outweigh the bad things. But there's only one reason to launder money, and that's because you earned it illegally.
What the parent is trying to argue is that the entire idea of money laundering should be forgotten and there should be no negative public perception of money laundering. What I'm arguing is sure, maybe people shouldn't go to jail for money laundering by itself, but there are zero legitimate reasons to launder money. The very fact that someone has gone to any length to hide the source of their income means they've committed a crime. Not the crime of money laundering, but the crime of whatever they did to earn the money. Because if they didn't commit a crime to earn it, they wouldn't go through the trouble of hiding it. Money laundering is probable cause for further investigation.
His argument sounds to me like people who argue that since the Constitution doesn't say the government can collect taxes, that means taxation is theft and we shouldn't pay them. It's the libertarian ideal that money is private property, humans are inherently good (unless they've won an election), and laws don't apply to you if you just believe it hard enough. Unfortunately that's not the way the world works. In reality, where there is smoke there is fire, and where there is money laundering there is someone concealing a crime.
I agree that a front is a reason for someone to be suspicious. Find a laundromat doing a million a day? Sure, investigate them. But that alone should not be a crime.
That's not even an argument. That's the lack of an argument. That's throwing a temper tantrum and saying "but I don't wanna!"
It's a sovereign citizen argument and I love seeing YouTube videos of people telling the police that exact thing.
Someone who launders money for a hitman or human trafficker is enabling the hitman/trafficker's business.
If you help bury a body, you're guilty of something. If you help clean a violent criminal's money, you're guilty of something.
The launderer's guilt is only "made up" in-so-far as murder or human trafficking are "made up".
(Re: Drugs, sure. The correct solution here is to legalize drugs.)
“Crime” is not a thing that exists aside from laws defining them; all crimes defined in law are equally “made up” (and, for the same reason, equally “real crimes”.)
You could make the case that money laundering itself should not be considered a crime, but it should be strongly considered with other evidence of wrong-doing. There are very few legitimate reasons to go out of your way to conceal the source of your income, so in doing so you're already behaving suspiciously.
Like it's not illegal to swerve back and forth in your car without ever leaving your lane, but if a cop see you doing it you're probably going to get pulled over. Because the only reasons you'd be swerving like that tend to be actual illegal activities.
