Past a certain point, it becomes indecent to rule as if you are a king.
Simply because you look ridiculous being all mighty and holy when in fact, you are no more than a frail piece of life that's hanging on to past imaginary glory.
Also because your kingdom no longer counts faithful soldiers standing in line for that glance/word of approval from the king. That kingdom is now a fiefdom with warlords who specialise in covert operations complete with artful camouflage and guerilla techniques. That kingdom is a snakepit.
