What might be the consequences if citizens were not required to pay taxes?

For the answer to the question above, wWithout taxes, there wouldn't be a government. A government needs money to run. That cash flow comes from the government's citizens. With this money, a government will build an army, schools, libraries, hospitals, and other public programs (There are two main different type of taxes in America, income tax, and sales tax). Without these programs the country would fall apart and into anarchy. This is why people shouldn't be too pessimistic about paying taxes because technically they will just come full circle and benefit you.
