I believe all "Royalty" should be discarded as an archaic throwback to pre Democratic times...

There's something to be said about separating one's leadership into symbolic vs. pragmatic.

The symbolic leader - the figurehead - is the one that you trot out for weddings and funerals, for signing important papers, and making stirring rallying speeches during times of hardship. It's a public relations function, when you get right down to it. They have little real political power and are very carefully circumscribed in what they do or can say.

The pragmatic leader is the functional head of the political apparatus. They determine policy and enact its execution. They can often do the necessary but unpopular thing (for better or worse) because the figurehead serves as a distraction. They are usually smarter than the figurehead (though not always) but they are also far more disposable.

Trump wants to be a King. He wants to be a figurehead president, and he has nearly no interest in actually governing. This means that there's a power vacuum in the US, because Trump has all the power and attention but has abdicated most of the governing responsibility.
