You pay taxes on what you own. But what you own is entirely an artifact of government, and government laws. In effect, the government is using the threat, or action, of coercion, to stop other people from taking your property. They are stopping your employer from making you work for a month and then not give you your wages. They are stopping someone with a gun, or someone with a lot of "friends", coming and demanding your house, or your watch, or taking your week's shopping off you when you leave the supermarket. They are stopping the bank from saying "you put money in but we are never letting you take it out". In return for you being given the right to own and keep property by the government in safety and security, you give up a very small proportion of that property to the government, which it can use for any purpose which is legal under the constitution. Describing taxes as theft is both intellectually dishonest and monumentally stupid.
Which is all I have to say on that subject. Apologies for the derail.
The government does not determine what I own, or don't own. I, nor you, derive property rights from the government. If you and I lived in Somalia, for example, and we made a transaction for a widget, what rights to that property were given to me from the Somali government? (trick question)
Now, to you use your own words, to claim the government is "stopping your employer from making you work for a month and then not give you your wages" is itself "both intellectually dishonest and monumentally stupid." Property rights are a human right. If property rights weren't a human right, and were derived from governmental powers, then why was the 4th amendment even necessary? Afterall, according to you, those rights were only granted out of the goodness of the governments heart.
Next, the government is not a union. They don't prevent my "employer" from making me work for a month without pay, or even prevent me from working long hours. Nor should they. Pay for work is a contractual agreement between you and your employer in which they give you goods (cash) for services (labor). Before labor laws, people still worked and were paid as they should have been. Even after labor laws, companies regularly hire employees they can't pay and then withhold pay after services are rendered.

Now you go to another incident that happens quite regularly and the government has no ability to stop.
http://www.mysanantonio.com/news/local/article/Couple-was-on-Facetime-when-during-an-armed-10414434.phpSo tell me how the government prevents armed robbery as you described above? They also don't prevent banks from going out of business, or investment firms. Did you miss Lehman Bro.s? None of these things are prevented by the government, so please tell me how in the world they are justification of income theft? But as you stated, I'm just monumentally stupid. It's funny that you talk about "safety and security" and the constitution when Ben Franklin stated this much "Those who would give up essential Liberty, to purchase a little temporary Safety, deserve neither Liberty nor Safety." The quote may not be 100% correct, but I feel the point is still fairly well represented.
