Benjamin, you write better than I do, but I disagree with the positions you are taking in.
If there are two options, A and B, then everyone can know that C is the correct answer but also that it is not provided. D may come to mind as well. As the author, you should have pointed out that you were delivering a limited perspective on all choices.
You find yourself in very good company, however. I love Plato, because he is almost audible in my ears when I read his words. But he jumps from If not A then B, to another If not A then B, all the way until he removed your shoes and socks, clipping your toenails.
The world is not a two-part series. There are four parts. Here are the ways nations can politically organize themselves:
A: Nations with a single ruler or ruling group (like China or Cuba)
B: Nations with two rulers or groups (like the UK or USA)
C: Nations with a couple of groups ruling (like Germany and Turkey)
D: Nations with a large number of distinct groups ruling (Like Finland and Spain)
Those are the choices, and each has their own specific game to play for those in power (and those not in power). I hope you recognize how your delivery is based on some of these options, and not on all options.

If interested, the four choices create a pyramid, since that it the model in which ultimately duality is forged. The singular top is opposed by the four bottom corners; the four bottom corners are doubled oppositional pairs.
This is further explained, for instance, in this article:
You are a good writer. I have to give you that. : -)
