Hmm. I have a hard time believing that you are a Libertarian.
The federal government has a right, and an obligation, to step in and prevent such actions in order to further the capitalistic system we have, despite its general Laissez-Faire approach.
The fed has the "right" to step in when fraud or physical force is used. Not when people persuade others to freely choose a product. The problem people have with MS is not that there is no choice, but that the choices aren't sufficiently convenient.
