Not to me. He acted as an engineering consultant or manager in the courtroom. Managers and consultants on engineering projects rightfully require licenses, even if they do nothing but talk in meetings.
Yes, absolutely. How is that even relevant? Are you implying that it's acceptable to violate the rule of law when the government makes a mistake? Do you shoot your mailman when they mis-deliver a letter?
The reasoning is not circular, full stop. Just because the government both (1) deals in licenses and (2) can be sued in court does not make the situation logically inconsistent. You're confusing collusion/corruption for circular logic.
