From Wikipedia: Taxation as theft

Thought this might fit in well with our discussion of civil liberties.

A theft is - among other things - a violation of one's civil liberties, one that is done regularly by governments. And since taxation is a concurrent power, this happens by all governments.

The position that taxation is theft, and therefore immoral, is found in a number of political philosophies. Its popularization marks a significant departure from conservatism and classical liberalism, and has been considered radical by many as a result. The position is often held by anarcho-capitalists, objectivists, most minarchists, anarchists, right-wing libertarians, and voluntaryists.

Proponents of this position see taxation as a violation of the non-aggression principle. Under this view, government transgresses property rights by enforcing compulsory tax collection, regardless of what the amount may be. Some opponents of taxation, like Michael Huemer, argue that rightful ownership of property should be based on what he calls "natural property rights", not those determined by the law of the state.

Defenders of taxation argue that the notions of both legal private property rights and theft are defined by the legal framework of the state, and thus taxation by the state does not represent a violation of property law, unless the tax itself is illegal. Some defenders of taxation, such as socialist Matt Bruenig, argue that the phrase "taxation is theft" is question-begging, since it relies on presupposing a particular theory of property entitlement.
