Do you think the Royal Family's work is sitting about eating swans?
All of the senior Royals are patrons of institutions and charities and their letters to businesses and investors releases millions of pounds of funding. I doubt a begging letter from say, Liz Truss (as nominal HoS/President/PM) would garner such input. They also visit countless events - many not of their own pleasure and several per day - to bolster public awareness and recognition of organisations who otherwise would go unspoken, yet are on the evening news all of a sudden. They also, and in particular the monarch, provide a totemic beacon in times of crisis. My father's generation were for example, very welcoming of the king and queen visiting wrecked cities during WWII, in the same vein HMQs addressing of the nation was particularly well received in the teeth of the pandemic. Who would do that in her place? Who has that gravitas? Who has a face and a voice so recognisable to centre a pissed off population, pissed off with being locked up, jabbed, lied to and denied basic contact with loved ones?
That crown is fucking heavy, you need to acknowledge that.
