ELI5: why does the queen still have royal riches and fame even though she has almost no authority over the British people's?

The British Monarchy is, for both Britain and the whole United Kingdom, a sort of living monument.  People usually talk about figureheads dismissively, but in the case of the Queen it's a very serious job, and it makes a real difference in the life of the country. 

A country's monuments and other symbols (flags, anthems, etc.) give its citizen a way to think about loyalty to the country separately from the country's politics. This lends stability to the country's politics, and a sense of unity to the citizens, because everyone understands that the country is bigger than just whatever people are arguing about right now.

The fact that Queen Elizabeth II is a human being makes a her even more effective monument, because people like her as a person. This personal connection ties very powerful and positive human inclinations together.

The whole thing also strikes me as incredibly british: as a "living monument", as I've called her, Elizabeth II's job is to be the most respectable and polite person in the world.
