Infants can't sign contracts, and we don't tax infants anyway because they don't meet the income requirements. Your comparison to wolves and sheep is not apt -- the "violence" of taxation is only as punishment for reaping the benefits of previous payers and not abiding by the rules the common voters agreed on. You are under no obligation to reap those benefits -- in fact, society is perfectly happy to give them to you for free (albeit minimally) in the form of welfare, and charities are satisfied with giving you free food and shelter should you find the system of commerce and taxation too burdensome. That you are not afforded the extended benefits gained by common taxation at your pleasure and rate without yourself contributing is not theft in the most basic sense; it's more like an obtuse mischaracterization. It makes an interesting civics thought experiment, but nothing more.
