I hear you, but that’s akin to thinking ‘why do I need a 1st amendment, I can say what I want’. Or ‘why do we need the 2nd amendment, we already have some guns’.
The adoption of it as law is to shut down the federal fight against privacy products, which is an end-run at prohibiting the exercise of the rights we know we possess. These charges brought against privacy product developers in the Bitcoin space is an encroachment against a right we know we have, but that isn’t constitutionally protected, and could become explicitly illegal or merely implicitly by allowing precedent to dictate outcomes in court. Let’s not leave it to the lawyers of bureaucrats to determine the fate of those developers that face charges for doing no wrong to people, rather only being guilty of restricting the power of the state.
