In what way does this old man with too much land bring calm and sanity to Britain? His resources should be given to the people as museums, there is no need for the monarchy to continue to profit off of land and wealth that should belong to the people.
Having a monarch makes it harder for the elected leader to run amok. Compare the UK with other near powers that got rid of their monarchs - Russia ended up with Stalin and Putin, France got Napoleon, Germany got Hitler.
It's a bit like Chesterton's fence - don't remove it until you understand why it's there.
Another issue with the idea we should scrap the monarchy in the name of democracy is the actual democratic voters are strongly in favour of keeping it.
