Ive made my case.
The elected officials of this country, a democratic republic, ushered in taxation. When you take a job, or rather earn income in this country, it is a known fact that you pay taxes on that income. The tax money may be used in ways you don't like, but that is not the question. The tax itself was agreed upon by the people of the United States. In our society, majority rules. That is the way it works when you don't want chaos.
Secondly your entire concept of your property, that is your money/earnings are made possible by a government that backs that money.
I think that you are saying that YOU, the individual YOU has not consented to have taxes taken from you. The problem with that line of thinking is that our country is not based on individual rule, but rather majority rule. With some exceptions that SCOTUS rules on. Since you choose to live/work in a country that is based on the concept of a democratic republic, then you abide by the rules put in place by the majority, or you work to change those rules, or you choose to live where the rules are different.
The people of the US have elected officials that imposed taxation. Your beef is with the majority of the American People, not the tax collector.
OK, we can rest on it then. You've made your case. But your case still does not provide a convincing argument that compulsory taxation is not theft. You say majority ruiles! Rent! Country club dues! Move somewhere else! Abide by the rules! All fine and good in justifying the theft. Still, it's theft by the use of force and violence.
