I am not in a position to violate it but simply disregarding it would result in what, some enforcement action to comply which has no basis in law? IRS used to “regulate” tax preparers. Preparers refused to comply, the IRS sued and lost in every circuit. Just because the government says it is so, does not make it so unless there is a basis in law they do or require something.
I do agree, that filing a false statement will result in your prosecution regardless of the legitimacy of the reg.
No document signed under duress has legal validity.
No rational person would say that agreeing to surrender one’s First Amendment Rights while under the threat of having everything you own seized was anything but duress.
The courts would cheerfully enforce it though. (Lawyers and judges have assets too!)
Good luck even hiring a lawyer when the IRS has confiscated every dime you have, padlocked your business, and is holding every asset pending the outcome of your IRS trial, in IRS court, with an IRS judge...
Or you could just get a TCMP audit (look it up) every year for the rest of your life.
