Makers of 3D-printed guns operate by the motto, “Free men don’t ask permission.” They don’t ask the State for permission to bear arms. They don’t rely on gun manufacturers to make a gun that they’d like to see developed. In doing so, 3D gun printing functions parallel to, and outside of the legacy model of regulated manufacturers producing compliant and serialized guns that can only be bought through third-party licensed firearms dealers after passing a State background check. A “Bitcoin circular economy” runs on the same principle. Free men don’t ask permission to transact with each other and don’t rely on the legacy third-party financial institutions that operate in tandem with State authorities.
