That way, I can add a Platonic philosopher-king system.
Always a great idea, since it makes for such an interesting outcome. Plato's ideal [1], when completely implemented, is basically the "prototype blueprint" for the entire political tradition of totalitarianism(/collectivism) in the West. By which I do not mean that he was a nazi-avant-la-lettre, or a Stalinist-avant-la-lettre, but rather that the tradition that eventually produced those to a considerable degree originates in Plato's work. (With the further caveat that he didn't really invent most of the pertinent ideas, but
did end up being the one who first codified them into a unified 'ideal'.)
[1] Naturally, there is some debate on what Plato actually wanted. Was the radical presentation of his political ideal the goal, and did he suggest more moderate plans elsewhere to make (steps towards) his ideal more palatable in the real world? Or did he actually want those more moderate reforms, and did he merely posit his more radical vision in order to draw people's attention to his work? I lean towards the former, because absolutely nothing in Plato's work suggests that he was a compromising type. And besides, his whole thesis was that the pure idea is good and noble, and his primacy over imperfect instantiations of that idea. Which suggests that his radical, 'pure' vision was what he truly wanted, and his more moderate, 'practical' proposals were merely lesser instantiations of his true vision (i.e. small ways to bring the world closer to his true ideal). In any event, going with the most "pure"/radical version of Plato's proposals would be the most interesting narratively no matter what.

All of which brings me to another idea for authoritarianism, namely a purely Hamiltonian USA. I think of it now because Hamilton is also occasionally presented as "supporting purposely radical notions in order to get a 'compromise' that actually reflects his true wishes". And in that case, too, I don't buy it. As I have reasoned elsewhere:
This notion is accasionally raised by people who agree with Hamiltonian policies in general, but are forced to admit that his actual personal ideas were way too far out there. It's an attempt to defend his legacy from himself. the fact that he supported the views I've outlined in private correspondence as well pretty much underscores that he wasn't "trolling". He really meant it. (The idea that he was being purposely radical to force a 'compromise' that was actually in line with his real views also goes against everything we know about his usual behaviour: he was a very convinced, zealous guy who never even considered that his own views were imperfect. Not that he was the only one like that, but it rather shows that "crafty tactics to pretend to be more radical than he really was" are completely out of character for him.)
At to why Hamilton's ideas would work very well in a chapter on authoritarian systems:
Hamilton's ideas (...) were a certain recipe for dictatorship and ludicrous social stratification. To wit: he wanted a president for life, elected by Congress. I fact, he wanted this president for life to be officially an elected king. He wanted Senators for life, and he wanted only people who had been officers in the ARW and their direct male descendants to be eligable for Senator. He wanted the states reduced to mere provinces, and a central government essentially free to do whatever it wanted. (The clauses empowering the cental government would be far broader, and the Bill of Rights -- which Hamilton didn't want -- would not exist at all.) He also wanted explicit primacy of the executive over the legislative (which would in effect make Congress a glorified advisory body to an all-powerful executive). He wanted a stong standing army, and he wanted to use it to actually start conquering stuff-- beginning with a war to take Louisiana and Florida by force. He also favoured restricting religious feedom to relatively mainstream Christian denominations, and making the USA officially a protestant nation.
In short, if Hamilton had gotten his way, the USA would be an aristocratic monarchy(-by-election), highly militarist, and way more WASP-y in every aspect of its being. It might not be literally "insane", but it would suck immensely.
Finally, I'd say that Hamilton getting his was 100% would have resulted in something totally alien to the OTL United States. No compromises, no gradual developments, no embedding of Hamiltonian structures into Enlightenment values... just the enforced imposition of a centralist, militarist quasi-autocracy with an elitist mindset and a reactionary culture.
Finally, more suited for the "libertarian" chapter, one could add the exact opposite of a Hamiltonian/High Federalist wank, which would of course be a Jeffersonian/Anti-Federalist wank. Which is basically the old "re-worked Articles of Confederation instead of a new federal Constitution". The USA as a decentralist, confederal union of states, wherein Jeffersonian ideas enjoy cultural supremacy.
Of course, this might be deemed too similar to
@Ephraim Ben Raphael's "Federated States of America" (already a decade old!), which is also a sort of libertarian-leaning, small-government sort of states' rights wank. But I think that, although I love that entry, it is very much a product of its day. Particularly the ending, which implies that a mortgage crisis much like the 2008 one from OTL is looming, has always struck me as narratively clever, but not convincing. (A right-libertarian system with a gold standard etc. would have problems, but not
that problem-- on the contrary, in such a world, a big social issue might be how
difficult it would be for less affluent people to get any credit.)
I think that writing an entry about an alt-USA that has been very decentralist, *libertarian and Jeffersonian from the very outset would be worth the effort. It would, at the very least, be a cool contrast to the Hamiltonian one.
Anyway, I assume you want to do the one on Platonism yourself,
@rvbomally, and maybe the two other suggestions pique your interest as well-- but if you think they'd be okay as entries but would prefer to avoid the hassle of writing them, I'd be happy to do it and send them in for review.
