Right, if you're looking at the entire country, but if you can draw a Lithuania shape that's got Lithuania-like properties, you should expect Lithuania performance within that shape.
Naturally, the big thing is that labour costs dominate costs of everything, so we won't have gig fibre available for Lithuania costs. But the fact that we don't have gig fibre for any price universally in that region is mostly because they have the leapfrogging effect in Lithuania - they were later to the Internet than America. i.e. the size argument is a facile false explanation for the absence of the things because within the areas that have similar properties we'd expect similar performance.
In time we'll see gigabit fibre come to America, not because there is an absolute cost concern, but because as it comes time to upgrade aging infra we'll just put what's best at the time in, something that would be impossible if there were true geographic barriers.
