I used to work as a scholar of Britain (specifically executions in Early Modern England, but you pick up a lot along the way) and I've tried to explain to a lot of people the amount of influence and control that the monarch actually holds. I'm not sure that this is such a bad thing. The Queen can't create legislation, she can restrain it. She is purely a moderating influence in this sense. She could, in theory, name…
She used her powers to get an exemption from transparency laws with regards to her personal wealth: https://www.theguardian.com/uk-news/2021/feb/07/revealed-que..., and Charles did the same to ban his tenants from purchasing freeholds: https://www.theguardian.com/uk-news/2021/feb/09/prince-charl....
This constitutional corruption of our laws by the most privileged family in Britain is indeed a bad thing, and one of the many reasons why the monarchy should be abolished.
Also, every member of the royal family should be stripped of their wealth and exiled.
