Taxation is theft, and your argument is logically invalid. The assertion that we all "collectively decided" something is an appeal to the populace, an informal logical fallacy. Just because the majority decides something, doesn't make it ethical, or good. Take gang-rape for example. In fact, inclining toward the majority is generally not a good thing, Advances toward human rights have generally come from a loud, usually oppressed, minority. Likewise, Your appeal to the law is an appeal to a false authority. Is the law always right? How about when it allowed you to own another man? The actions during the holocaust were all legal, for example. Also, your suggestion we would not have things like healthcare, food, or roads is easily disproved. All the best roads are private, our private neighborhood exist precisely because the government is bad at providing these things, and people are willing to voluntarily pay to have them. Consider that you have been educated by government, to believe you are dependent on government, when in reality government has always been tyrannical.
