What of the nation state?

[Beskar]

What benefits does such an organization offer that, say, the UN, the WTO, Either this proposed World Government has real power, and is thus subject to the concerns I mentioned in my previous post; or it has extremely limited functions, which makes one question whether such an organization is worth the time and resources it would take to create and maintain.

Yet both UN and WTO are cut down versions of a World Government. It would also bring an end to war, destroy the social constructions of imaginary divides on a piece of paper. A World Government would be far better as it would force the nations to actually comply, to bring human rights and prosperity to all.
