I've seen nothing new. The IRS has failed to address
redeeming lawful money. In itself further evidence your interpretation of the Federal Reserve Act is correct, all these years later.
Some may claim to redeem lawful money, file, then wonder why they don't get to the end zone, tax-free. As a successful nontaxpaying filer for years I can say you need to actually redeem lawful money, and be able to provide proof. You can't claim the ball crossed into the end zone, when you haven't established yourself as a runner (redeemer). You have to establish yourself as a “runner” first before the goal line means anything. To establish yourself as a runner (redeemer) you have to complete the catch.
Jesse James never completed the catch. A receiver has to “survive the ground through the catch” and he didn’t.
Merry Christmas!
