The daily life of a medieval king

And that works very well even today when you are high enough to get a personal secretary. For the engineer who always shared the secretary with several others she didn't know you as well, and in any case their preferences were not important enough to consider (you don't get first class options).

Even for my boss, outlook is a force multiplier over a secretary because he (happens to be he today, has been she in the past, and likely will be again in a few years) doesn't have very many things where knowing preferences matter and doesn't have such complex scheduling needs that a human needs to do it. The ability to schedule his own meetings is much more powerful than asking someone to do it - while it might take more time to do it he can see that by not inviting one person the meeting can be had sooner and that is a much greater multiplier than the time saves by having someone else who not knowing those details delays the meeting until everyone can be there.

Yes when your situation is such that a secretary can "understand you, and act on your behalf in the matters you delegate, knowing what outcome you would choose yourself" it is a force multiplier. However most of us are not really that different from anyone else and even where we are we are not allowed the level of differentiation. We also don't have nearly the ability to delegate things, much less enough things that someone else can delegate them on our behalf. And so for most of us outlook is a force multiplier over the secretary we would get.

As for listening to commoners, I'll accept the possibility of kings that wanted to be accountable to their subjects. The problem isn't the king, it's the nobility. The nobles are going to be filtering the commoners that get to talk to the king, because the king isn't allowed to know any commoners directly. Hell, they might not even be able to speak the same language at all. England's kings all spoke either French or German for a long time, and French wasn't so much the language of France as much as it was the language that France's ruling class spoke[0].

Even if the king could understand commoners and had unfiltered access to them, it's not guaranteed that they could do anything with that feedback. Say, a peasant complained about what they pay to their lord. Does the king actually have the power to overrule the nobility? Will the nobility depose the king, or start a civil war that destabilizes the country?

The game everyone's playing is ultimately to convince subsistence farmers to "go big or go home" - i.e. to overplant and overproduce food, at the risk of crop failure, so that the state can seize some of that food and eat it themselves, nominally in exchange for "protection"[1] from rival states whose main difference is that their king is fake while yours is rightful. In other words: the king and nobility are wolves, the commoners are sheep, and it's bad form for predators to befriend their prey.

[0] At least until France erased their own minority languages in the 1800s and forced everyone to speak French, which I'm pretty sure counts as genocide

[1] Identical to the 'protection' paid to a mafioso

I think you could make a good case that the title is a little sensationalistic, but you could pick at US civics class in exactly the same way (and not just in recent history). The branches of government we learn about fail to include (or at least emphasize) the fundamental role of regulatory capture, lobbyists, and opaque/undemocratic three-letter agencies in real-world governance. Not to mention the fact that even the founding of the country was based on high ideals that were highly caveat-ed ("all men are created equal" unless those men are property).

Regardless of the extent to which ideals are lived out in practice, to many people it's notable that those ideals are there at all. In my experience as a US citizens, most people educated here seem shocked to learn that there can be any ideals behind monarchy besides divine right of kings/"I am the state" [1].
