The Warrior King?

Some kingly thoughts; in the past, the king was required to be in the front lines of battle, to expose himself to risk of possible death or disfigurement. As a consequence, with power came privileged and potential skin in the game and downside.

Now the problem is all these new kings, they are somehow shielded from violence in war, no flesh in the game.

A simple thought I have is maybe we have to make this warrior king idea good again; for example, imagine like a king Leonidas on the frontlines of battle.
