Yes, every country still needs a government. People are like sheep walking around with out a leader or authority. If the government were to disappear, the worlds citizens would go into a Chaotic downfall. Crime rates would sky rocket up. And the economy would fail. Too many people around the world rely on their governments for assistance like unemployment checks and protection from foreign threat.
If someone where to set aside the check of the "Executive Branch". The president would have alot of power and no one could stop him because he has so much authority.
Hope this helps
