absolute monarchy depends on the ability of the monarch to balance the power of two classes: the big bourgeoisie and the feudal landowners. As the second class is today non-existent, a monarch whose power resides in the big bourgeoisie alone will be forced to give more and more of that power to a bourgeois parliament, see modern UK. the only other option would be to partially restore feudalism, a feat that is impossible in a modern globalized economy. no matter how much you want it to be the case, a Restoration in the year 2020 is an impossibility in both an economic and a political sense.
tldr: even Neoliberalism Cat can cuck you, Grace, and that's pretty sad.
