The discussion on the value of monarchy is hotly debated around a quantitative measure of value, tourism vs maintenance costs. I do think there is a case to be made on the qualitative aspect of value. A monarch acts as a check for ambitious undesirables (politicians/hollywood types etc) from achieving the ideal elite rank in society, as no one can truly be king by definition, except the king. As such, they act as "power inhibitors" on the rest of elite society. Inhibiting cult of personality, the monarch instead reflect opposite values like devotion to duty, and restraint, instilled from birth. In summary, this seems like catastrophic insurance. Even if the probability is very low, the price to insure against a despot , would seem to be reasonable.
