I feel like growing up is realizing that the government is just a big gang. They do what they want and will enforce with menace what they want. They can change the rules, take your stuff and it ain't stealing because they said so. Sigh.
My takeaway though is that human societies abhor a power vacuum: no matter what my libertarian and ultraliberal friends imagine, there must be a strongman. At least with democracy, we have the opportunity to somewhat influence who that is.
