Yes, when you tax for something that is not for a power or function the government was ever given, it's stealing.
Nor is it necessary to have a government, it's by consent of the governed. If the people don't want it, they have a right to change it, abolish it, or leave it altogether.
And unlike Marxists with their word redefinitions, people means individuals, not some mass collectivized mob - of which the founders were opposed to.
No one has ever given up their God given sovereign rights. Anyone that says otherwise should be aware the Declaration of Independence among other things recognizes the existing fact that God is the Supreme Judge. He is the judge of us and of that, not you.
And for the support of this Declaration, with a firm reliance on the protection of Divine Providence, we mutually pledge to each other our lives, our fortunes and our sacred honor.
