Sure, and the monarchy could be abolished by a simple parliamentary vote, and the weekly meetings where the PM briefs the monarch on anything that could hurt the latters financial interests could be abolished even more easily.

Except the monarch is a billionaire with power over even more money and public opinion and elected representatives are rightfully afraid of the monarchy's well funded and well oiled propaganda machine being turned against them.

The monarchy never tried to help me save face, why build entire government processes which do nothing but that for them?
