No because a monarch is bound by the nature of his job. The nature of his job is to secure the realm, provide safety and collect income, just like every state ever did. If he does not do that, someone else will and he will no longer be a monarch.

besides whats going to stop the monarch from comanding this or that. If they are no cheack and blances ? Anrachy?
