Leaving traditions behind is essential to progress.
Maybe we should reinstate full control of the Catholic Church's Medieval Papacy, that was quite the tradition.
Except there isn't really anything that a
constitutional monarchy / parliamentary government is affected by a
non-politically influencing royal family that has its own money.
In other words: Britain's royal family literally does nothing for politics or anything else, they still are honored as tradition and as a leader.
Hey while the whole country and the rest of the would is focused on the wedding no one would suspect a mad man to melt the polar ice caps with his doom laser!
Tone it down there skippy, whoa.
