Taxation is legalized extortion. We don't just pay taxes to avoid prison terms and penalties; we pay taxes, ultimately, because State agents will kill us if we don't pay taxes. The State is like the mob. If the Sojourners deem the analogy strained, they should try not paying their taxes and then resisting arrest. See what happens then.

So the better question is "What would Jesus extort?" or, perhaps more incisively if less succinctly, "In furtherance of what socially desirable end would Jesus menace somebody's life and property?" To pose the question is to answer it.
