Taxes corrupt. Taxes help mainly the richest people. I am not privileged, I am a tax slave. Healthcare, education, insurance, food, and other services could easily be paid directly by individuals, without the government taking its cut to bribe bureaucrats or serve shady corporate decision-makers. In a world without taxes, human interaction would be based entirely on voluntary trade. The only area I am unsure could function without state violence is defense against other violent states.
