Jim about theft again

We often have this discussion. Is taxation theft? I argue that that is not the right word to use, even though it's true that something is being taken from you under the threat of force. Theft implies something unlawful and since the government is the law, however unjust we may think it is, law is law and not theft. 

Jim views property rights as part of one's natural rights. I view property "laws" as equal to the infamous "social contract" ... as generally agreed on arbitrary social constructs. This valuation I make leaving out moral judgements. Perhaps that is a mistake. Jim's beliefs about personal and property rights are deeply tied to morality. What is right is right. If there is no moral relitiveism then, it follows that there is a "natural" law, natural rights.
