Making "demand for lawful money per 12USC411" can only be achieved through a PERSON. Said PERSON is a created 'United States' vessel, TITLE to which exists somewhere but NOT with you. The "demand" facilitates the "they shall be redeemed" portion. The debt is purchased back by the original issuer and the obligation to foreign or private interests is diminished. It is the public venue that realizes the benefit of diminished obligations and debt extinguishment via "demand made per 12USC411".
