I voted no, but only because we are centuries away from it being possible. The global economy has only become truly global in the last 30 years. After hundreds of years of tighter and tighter economic ties between countries their will be more and more pressure to standardize laws, and economic conditions between countries to promote fair trade. Eventually this will lead to a single governing body with power, and ultimately a single government. It's already happening to some extent, but it's a slow process that will take centuries to really get to the point where their is a global government.
If history has taught us anything it's that economics trumps all, and current economic pressure is towards a global economy and eventual global governance.
