Maybe, but what "tribe" are you part of is completely fluid. Your tribe can be extremely inclusive or exclusive.
> Grand unification of humanity is a good ideal, one we should work towards, but it's not something that will be possible within our lifetimes.
And it is quite of inevitable as communication and travel becomes cheaper.
> I don't want a European superstate because I disagree with most people that would live in it. My ideals would no longer be represented by my government. I think that's enough reason not to go for complete European unification.
That is easily an argument against any form of government. No country would exist this way for good or bad. But they exists. As you said, bigger communities are a matter of time. What it would have been an impossible union 100 years ago it makes a lot of sense today.
