This is all about the intent of the writer of the law and the subsequent code. Who here has first hand knowledge of such intent and/or is certified to interpret either?

Is the "demander" also the "redeemer"?

Does "They shall be redeemed upon demand" mean that redemption of notes is an automatic function/effect of a demand made?

Does it mean that someone who is authorized to redeem "shall" redeem when a demand is made? When? Isn't "shall" a future tense verb?

Unless someone here can say with 100% certainty that he/she has first hand knowledge of the intent of the writers, I would suggest that our only concern is to make the demand for lawful money known through the vessel used for such activity.

My opinion is that if it is not we that are the trustees, then we have no business declaring that something has been redeemed; is it we who are buying something back?

Our only obligation, if we wish to be outside the scope of the Federal Reserve's jurisdiction when handling their issued notes, is to make the appropriate demand and keep a lawful record of our transactions.

Whether the obligatory party chooses to fulfill the duty of redemption or not ("shall") has no effect upon our affairs.
