A country, BI, is a recognisable social grouping, generally along the lines of race, culture, or some other common denominator. And yes, it matters to very many of the species, because the species is a social one whether you (or others) like it or not. If you're not, you're an exception. Maybe you're the future too, but it's a way off. I'm afraid mankind's social development lags behind the technological by some margin!
