I would only be for a world goverment if I was in charge.
I would focus only on my own pleasure, since that is what the world wants (see african dictators. I would build massive, billion dollar pleasure domes all over the world, ruining economy after economy.
Believe me, after I get through with it, the idea of one world goverment will be dead. (as would me, the imperious leader, since a coup would have to force me out. but what a ride!)
My goals would be more modest;
A)Monday would be Beer and Ribs Night. An official legal holiday in which people would be required to shout, ALL HAIL BEER AND RIBS!
B) I’d gather the best minds on the planet to create a sport in which the trebuchet played a major role.
Beyond that, it would be pretty much business as usual.
