I went through a vehement anti-monarchy phase when I was younger, since then I'm starting to appreciate the idea of a head of state who isn't a career politician that campaigned or even bought their way into office.
This, after all, is how wars get started.
Edit: the dire circumstances being, of course, WW3 - the subject of the Queens' speech.
Having said that, I prefer having the Royals to an elected non-ceremonial Head of State. Having the Head of State separate from the head of the executive branch of government seems like a good idea to me.
If we were all loaners things would be much worse. You might not have war, but you would have lots of individual killing, and very little progress.
Your best option is not to fight it, but rather to use it: Get people in various countries to consider themself all part of one group. (One of the reasons I think the Olympics is a huge impediment to world peace. I almost never think of MY country as better than YOUR country - except during the Olympics.)
Bit of a selection bias there. Those of us who don't care just tend not to talk about it.
