Again, you are confusing yourself. The administration of a taxation system may be rubbish but its is still a taxation system. Tax is taking legally; theft is taking illegally.
I think what you are trying to say is that you don't like the idea of law and therefore all actions that are "legal" under the present system are outside the law for you. Its a valid viewpoint but you can't use words like "theft" or "property" if you don't like the idea of law. They are legal creations.
I'm not confused. My logic is sound. I know exactly what the definitions of property and theft are. I've got a treatise on law that I spent much time perfecting. It has very few flaws, if any. For the most part, property can only exist if one man may possess, own, or control an object independent and exclusive of another person.
The second you violate that principle, and despite your reasoning (collectivism, majority rule, taxation, norms, societal coercion), the concept of property goes away. It dissolves into some version of "might makes right" or the "strongest survive". If you believe in such things, then there is very little need for laws.
Laws are created out of the need to protect the individual life, liberty and property of man. If you wish to play the game of prey and predator, then we can argue the finer points of superior species or top-of-the-food-chain animal behaviour characteristics.
EDIT: A law ceases to be a law when it conflicts with itself and its own principle.
