I never mentioned anything about a command economy? I don't even believe in a command economy? I cannot really address this point since I am unable to grasp where it has came from.

As for One Government, the main despotic regimes visible around the world are the main problem. Having a united democratic government would be far superior to ridding tyranny due to being able to act decisively and swiftly. Since my proposal of a world government would be federal and in a sense, similar scope to Belgium where the world could continue and government doesn't have much of a part to play, if at all, in the scheme of things. There wouldn't be many issues.

Think of things that plague this world. Country X having human rights abuses, Country Y being very hostile and arming themselves with nukes, Country Z who cannot even do basic maths and decimating their own economy. All that would be done away with in a simple way, since there would be a universal charter of human rights which everyone would be made to stick to and they cannot weasel themselves out of it. United World which could swiftly deal with despots who rear their ugly heads without spending tons of time at a conference table, trying to organise "who will contribute what".
