What's wrong with monarchy?
Republics have plenty of problems too.
In fact, there is no system of government, and neither is there any system of government that can last forever. As Plato said, systems of government recur in cycles, as each system of government starts off fresh and does things to improve people's lives in the polity, but eventually it grows old and corrupt and gets replaced with a new system of government after enough pushback from both commoners and elites and the cycle begins anew.
This life-peak-death cycle applies to every system of government and to every government. It is inescapable, like a law of nature concerning sociology or how human social institutions develop and then devolve. All our institutions have a lifespan.
And what there is to recommend monarchy is its naturalness, meaning the fact that something like 99% or more of all the political systems to exist since civilization began have been monarchies.
Yes, every monarchy has died. Every dynasty has died to be replaced by another, and then every chain of dynasties in a monarchical system has ended as well, to be replaced by a whole new system of government or even a new civilization. But republics and democracies or whatever systems we live under today that were inspired by the Enlightenment will grow old and die too. In fact they're already very old and decaying, as is obvious from how sclerotic and corrupt they are, clear signals that they're in their final period of life: senility or old age.
At least with a monarchy, it feels natural. It's just written into human DNA to follow one ruling family regarded as royal and therefore a cut above the rest of humanity, even the nobles who, while noble, still aren't royal and are to the royals what peasants are to the nobles: a whole different order in the Chain of Being.
I submit to you there is an existential comfort to living under a system of monarchy, a freedom of not having to deal with politics and knowing all major
