If you buy a house, the house isn't really yours. You have to pay taxes in order to keep it, even if you don't need any sort of public service. If you don't use any sort of public health, you still have to pay it. The government asks you to take part of what you earned and give to them. If you make money and don't give to the government, they can take it from you by force; that is, they will enter your home, point a gun at you, ask you to stand down, and take your stuff. If you react, you might be arrested and locked inside a cage to live as an animal. Your crime? Not making money for the government.
The government is always the opressor.
