I don't know about the Corporate (FEDERAL RESERVE) money article that you posted.
This just seems to be a stretch. Having a private corporation or government entity issue private money, and that being the reason that the income tax can be legal seems like a stretch.
What about what the supreme court has said on similar things like this?
In Thomas v. City of Richmond, 12 Wall. 349, 20 L.Ed. 453, Thomas brought his suit to recover on notes issued by the city. As in the instant case, it was criminal both for the city authorities to issue them and on the part of the party who paid for them. Of this the Court said in 12 Wall. at page 356, "* * * The issuing of bills as a currency by such a corporation without authority is not only contrary to positive law, but, being ultra vires, is an abuse of the public franchises which have been conferred upon it; and the receiver of the bills, being chargeable with notice of the wrong, is in pari delicto with the officers, and should have no remedy, even for money had and received, against the corporation upon which he has aided in inflicting the wrong * * *."
