A few things stand out from the last few chapters of Hobbes:
Chapter 18, Paragraph 9: It is the right of the sovereign to decide what speech is permissible. Of course I recoil from this...but he's not wrong. I say that not to really excuse infringements of speech rights, but to note that even respecting speech rights is a choice. We say it isn't a choice, we say it isn't something the government gets to decide, but they do. And not just in the "fire in a crowded theater" sense and related matters, not just in those edge cases. The choice to respect laws and constitutional rights and court rulings is ultimately a choice. In a free society it's a choice that the government makes frequently and without much argument, but it's a choice. When you dig deep into the nature of power, that fact is inescapable.
And we saw on January 6 that respecting the foundations of a liberal society really is a choice, and it's a choice that the powerful don't always make, and neither do their supporters. We saw that some leaders choose illiberally, and ultimately their resistance failed only because other people in key places resisted them. How great or small you think the threat ultimately was, it was a threat, and it was a threat that was averted by choices.
Chapter 19, paragraph 4: Hobbes argues that monarchy is the best form of government because it ties the monarch's personal interests to the state and people. This is of course entirely incorrect, as plenty of leaders put their own interests ahead of their people's. However, leaders who put themselves too obviously ahead of their people tend to run pariah states. Perhaps we can say that a liberal and affluent society is more likely to be one where the leader sees the affluence and prestige of their state on the world stage as being in their own personal interests, and they thereby foster a dynamics and free society.
Of course that's idealistic, but the point of ideals is to ask what direction to push in.
I think there's a lesson for leadership: If your organization is one that everyone wants to be a part of, you and your organization will thrive. If you just want to get your own piece of the pie at the expense of others, you will hurt the place.
Chapter 19, paragraph 23: The Romans built a stable empire by bringing people in the provinces under the umbrella of Roman citizenship and rights. This gives some context with the modern interest in inclusion.
