I mean, there's a difference between writing an exemption just so you can do a thing without getting in trouble, and writing an exemption that is so obviously for the benefit and health of society/community writ large. I can't think of a crappier example to have used to have tried to make the point they're making.
The FBI didn’t write the law. And it’s not for the benefit of the FBI, it’s for the purpose of getting scammers off the street. Billions of dollars have been lost of crypto scams.
