> in short the Monarchy serve no real purpose in modern societies.

Id give it a bit more thought. Wierdly,monarchs seem to be the default in human societies throughout the ages.

Even our current system of government is modelled after monarchs. Supreme leader at the top, his second, close circle below, ministers below, bureaucrats below them, and finally us plebs.

Maybe our times make sense for cold, efficient technocracy. But monarchs were very human. Thats why we write stories about them in wonder and awe thousands of years later.
