Right out of the gate British leaders have a problem in acquiescing to having a king - flies in the face of individual God-given life, liberty including free speech against the gov’t, and free pursuits.
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.
