Agree with Fyron. World state = zero diversity = greatly reduced freedom. Today you can immigrate (in theory, at least) to another country if you don't like laws, customs or government at home. United world has same laws, government and equated customs everywhere.

World state is a tale of 60s, based upon opinion that brotherhood and love are main human stimulus. By 2000s this point of view is disconsidered once and for all. Nations don't want to unite, they want to fight. All multinational states were created by force and this won't change in future. State Earth will be a worst dictatorship in the history of mankind.

As a cyberpunk fan I prefer anarchist world of zaibatsu and independent anclaves. And it seems to me that this scenario is more realistic than "Empire Earth" future.
