If we were to rationalize all this and draw lines peacefully, what would be the typical size of a country? Would we chose no country at all, in a world-government? Would we pick the "city-state" model, as often advocated by libertarians?

Given the US perspective of polarized politics, how does it make sense that the strongly-held beliefs of one portion of the voting citizens should be foisted upon the remainder of the entire population?
Smaller government is more responsive to the local conditions and culture than is large government. And the inevitable abuses of the state against the citizenry will be limited in scope.
Of course, along with very small government, I would also advocate 100% free trade and very low regulatory burden, such that a small land-area country could still be an economic powerhouse.
So I think the original question is quite valid. There's a sweet spot somewhere between "as big as possible" (e.g. US or Russia) and "as small as possible" (e.g. city-states).
My gut would be that it's more determined by economic production and ethnic subgroups than some constant. Sufficient economic production to play competitively on the world stage, while grouping as many like or agreeing ethnic groups as possible (and preventing their repressing minority groups).
Or in other words, international jerrymandering.
Sadly, countries rarely are created as such, and are demarcated more along lines of conquest (which is a very weak signal of local culture, especially if the local civilisation has been around for 1000s of years but conguests happened 400 years ago) or even sometimes on what can only be described as kookoo political ideologies.
The benefits of large governments - uniform currency, uniform code of law - have been increasingly eroding and losing relevance, so I am pretty sold on the city-state model.
Some of them, like Denmark or Finland are doing pretty well, and have some of the most advanced democracies in the world.
