Yvain, here is a challenge. Many of your examples are weak versions of strong right-wing arguments that you do not accept. (by your remark about Schelling fences, it seems you're aware of this). I challenge you to replace each of these examples with a weak version of a strong left-wing argument that you do accept. Since policy debates should not appear one-sided, there should be no shortage of weak arguments "on your side." And it would be an interesting kind of ideological Turing test.

Perhaps I'm wrong about "what side you're on" and you already accept the strong right-wing arguments. In which case you got me, well done!
