Christ is King so having a king is not a defacto position of being against God-given life, liberty and free speech. But because of concupiscence it is really very difficult for civilizations and governments to have a king and monarchy that is truly just and fair but it is possible. It would take a truly humble and God-fearing sovereign to pull it off.
Until Christ returns as King of kings and Lord of lords to directly reign as worldwide sovereign over the earth, the best gov’t known to man is the Rule of Law, the just and sound U.S. Constitution.
The “Divine Right of Kings” is the Rule of Man which threatens the individual and fails.
Having a king flies in the face of the right to free speech against the gov’t. If you have free speech, then the “king” is more of an elected or appointed official.
