I left out some important context in my last post and so have added the following to the third paragraph:
Now, for those unfamiliar with the background, both Swann and Beck are market anarchists, as is at least one of the economists (Friedman) writing in the article cited. The other economists, at minimum, advocate a tiny State. The implicit complaint being lodged by Swann and Beck (in my own view) is that these economists justify their anarchism (or “minarchism”), essentially, on doing the most good for the most people (maximum utility) and not on what they see as the underlying fact of man’s individual and unalienable right to his own life without any qualification. I have great sympathy for that complaint.
