Well without government you would not have any organization, and everything would be scattered. Government is everything, they protect you from eating harmful foods, control currency, and even set laws to keep us safe. Without a form of government there would be no unity, and we would be like barbarians and uncivilized.
another reason government is not necessary is because the government is raising taxes for lower and middle class citizens and put theme in debt to the government and while the upper class is not paying taxes when they could afford them the government is taxing the "little guys".
The "little guys" are taxed because there is more of them, the tax system is set up so that the money makes it way back to the "little guys". The tax money does make its way back down to the "little guys" and it goes into roads and things that need upkeep. Without government and its taxes everything would go to hell and be falling apart.
