Oh, okay, so it's a license-to-practice restriction; that makes much more sense. Thanks for the clear and informed answer!
One could certainly argue about the fine points of profession legislation, but alas for the original poster, I don't see how this proves that the laws in the USA are "so massively out of control a normal executive violates criminal federal [law] a minimal of several times a year just doing normal business". (I can see how this might be true for copyright law, which is a particular portion of the law that is indeed massively out of control -- though even then, *criminal* violation is not *that* trivial -- but I am not sure there are any other examples.)
