The key thing to understand is that law absolves us of a need to be moral.
Put a fence outside of your lawn, and your child will not have to fear the road; take the fence away, and the child will learn to fear the road. Absence of law calls for the learning of value.
In much of the medieval world, people had to defend themselves, feed themselves, fight for themselves, and the people understood the difference between loyalty and coercion.
When you know the government will feed you when you're hungry, for example, then you know you don't need to work.
And when there's punishment for the crime of intolerance, you know you have to show "loyalty" to diversity unconditionally, otherwise you're labelled a racist.
The medieval world didn't trust anybody when it wasn't appropriate; and though it might have been illegal to renounce loyalty, the loyalty was still earned by the King, because it was important.
Point is, the way people thought and acted were different, because the circumstances were completely different.
And when a baby was born to become king, he lived with that role in mind his entire life, and was consumed by it, not just the pride of being king, but the pride of being a GOOD king. His goal was never intended to be crooked, unlike a president who can affect change for himself and retire with his family inna woods; the king knew it was his goal for his entire life to become what a king ought to be.
This work-pride was what made people more efficient, because the thinking is really simple. If I identify as a whore, then being a whore would be my main source of pride. If I identify with whores, I would become a whore. In 2 sentences, that's how you fix modern women. Anyway, the fishermen prided honour among other fishermen; and it was by the honour of their identity that they became good fishermen.
