It seems OP is, unfortunately, BU to think the monarchy will end with Charles, as many replies on here show that people are just content to be dazzled by bling, and by what the RF allow the BBC to tell them. People seem either not to care or genuinely have no idea what the queen actually does (or doesn't) do.
From the RF official website:
"The Sovereign acts as a focus for national identity, unity and pride; gives a sense of stability and continuity; officially recognises success and excellence; and supports the ideal of voluntary service. In all these roles The Sovereign is supported by members of their immediate family."
(PA, for example, is obviously giving valuable support to the monarch at this time).
So that's the official line: she's a HoS and HoN (head of nation) who supposedly makes us feel united. She "represents" us.
She is also head of that other bastion of national identity, the CofE, with its sub-1 million regular worshippers in a country of 65 million people.
And despite the queen being optimally placed (as head of the Commonwealth) to be a champion for equality, her actions speak much louder than the words she doesn't say to distance herself from racist, exclusive practices (remember, "never explain"). Her household's abysmal diversity record just can't mask its entrenched racism (just 8.5% of RF employees are from ethnic minorities - even our disgraceful House of Commons manages 10%). The queen even demanded (and got) exemption from equality and diversity laws:
(from the Guardian) "It is unclear when the practice ended. Buckingham Palace refused to answer questions about the ban and when it was revoked."
How is this family - which despises Catholics, Jewish people and ethnic minorities - representative of multicultural, multifaith Britain in 2021? How can people "look up to", "admire" or "like" the RF's attitude and behaviour?
Or maybe the monarchy really does represent Britain: a country full of small-minded, insular, backward-thinking people who are happy to blindly celebrate a family that's uncomfortably close to the Aryan nightmare of the 1930s.
The RF represents only itself and Britain's shameful imperialist past, and has to go.
And other European monarchies aren't great at staying out of politics either:
