Why do you believe in monarchy?

This post isn't meant to be hateful or anything, I just stumbled upon this subreddit and am genuinely curious as to why people here believe monarchy a positive thing. Because in a perfect world, I don't see why family should have any impact on who is put in positions of power, as opposed to your actual abilities and qualifications.

I am open to changing my perspective because until I discovered this sub, I never even knew that there were people who believed monarchy is actually a good system compared to its alternatives. But this is probably because I've never heard any real arguments supporting it.
