Just ignore him.. this is an insane legal "scam" that certain people are obsessed with. The govnt was sold out and incorperated, the federal law does not cover you, only your STRAWMAN "agent", ie the enumeration of your self (social security number) as an asset and not your physical body, and anytime the fed govnt makes you sign anything, instead sell them your autograph or refuse to acknowledge their jurisdiction over your state blah blah blah.

Its tired and now well known and several people have spent jailtime trying to adhere to this philosophy. Its almost cultish. I would recommend against taking their advice or even replying to them.
