Monarchs these days are (fortunately) more benevolent than ye olde days, and are looking to become bastions of calm and sanity in an era when democracy (FSVO democracy) keeps roiling shit up.
I say that as an American too, long live the King.
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.
Also, it's not symbolic. The king has to approve all laws, for example. The whole thing is disgraceful and has no place in modern society.
The last bill that was refused assent was the Scottish Militia Bill during Queen Anne's reign in 1708.
In Australia, my country, presenting law for Royal Assent is a rubber stamp, a symbolic act that transcends the current elected government houses.
Should "Royal Assent" be refused by the Crowns agent in Australia you'd see the country exit, the Crown is there for show, not to get involved or to meddle with the work of the elected Government.
I suspect Canada, New Zealand, et al are similar.
You could always point to an instance in which the Crown refused Royal Assent if you'd care to.
Don't gaslight people into thinking it has any real power.
The King has to rubber stamp assent, albeit with bloody ink pen, but it's symbolic like any other bit of pagentry.

The power it once had has been whittled away to F-all.
Magna Carta was issued in June 1215 and was the first document to put into writing the principle that the king and his government was not above the law.And I do not agree with your assessment that the king has no real power. A gentleman's agreement not to be a tyrant is not even close to good enough. I don't dispute it would cause lots of drama if the king tried to defy government, but he can do it. The guy is allowed to murder anyone he wants, he has full immunity from criminal prosecution! Is that a symbol worth protecting? No. It should be torn down and cast out.
Any respectable modern system of governance would not want even a whiff of an impression that it was led by a bloodline of kings. Yet, the UK and Commonwealth countries lean into it. A crown is a symbol of oppression. It's disgusting.
Btw, a king that misbehaves gravely becomes a tyrant, and if it is prudent, tyrants may be dispatched with a clear conscience.
