I'm not debating that government plays a role in establishing a functioning society. The level of involvement is clearly debatable. I personally lean more libertarian. Teachers, police, roads, etc. Regulated private industry can handle these types of things better. But that's just my opinion.
What is not an opinion is that taxation, particularly income and property taxation, is theft. The government takes your money against your will (you wouldn't pay if you didn't have to). Even worse, they take your money for simply existing on your own land (property taxes). And if you refuse, they arrive with weapons ready to take you to jail. That is by all definitions, theft. Openly, unabashedly taking your money. To spend on other people.
Now, you can argue that is a necessary thing to provide the society that "a majority" of people want. And maybe some of it is. However, it is still theft if you are the person choosing to not participate in the game.
