"Libertarians constantly encounter challenges to their criticism of the status (statist) quo which demand that we not simply denounce what exists, but present a detailed blueprint of our preferred replacement. I find this seemingly reasonable reaction tiresome in the extreme. First, our whole philosophy hinges on the conviction that no one, including none of us, knows how the world ought to be constructed: that "construction" should be the unplanned emergent outcome of free people's ceaselessly pursuing their objectives by peaceful, voluntary means. Second, if the house is burning down, must we offer an alternative to the fire before putting it out? If a viper is loose in our living room, biting everyone there, must we offer an alternative to the snake before killing it?"
