After opting out of everything, I bet they'll still want protecting by the US Army, Navy and Air Force.
What is the federal government supposed to be, if not to defend the land from outside forces and to defend people from destroying each other's individual freedoms?

I think that it would be perfectly consistent of their Libertarian viewpoint to accept military protection from the federal government. They just won't accept abridgement of individual freedom in trade for it.
