I agree that it is perfectly OK to Ban in such scenarios, and that the exact wording of the reason is not terribly important. Just expressing my thoughts based on what I read here. It seems obvious that the character was doing nothing that was requested and just sitting in the capitol. The fact that he was "draining the realm of gold' suggested that the most basic form of punishment, being kicked by his lord, was not attempted. It is just a matter of personal taste, but i would have preferred to try that before banning the insubordinate bastard (calling the character names, not the player).
