I purchased this along with Human Action by Mises and Rothbard's Power and Market (both Scholar's Edition, of course). I decided this would be a good investment, since I've just started to explore Hoppe's writing after reading a summary of his Argumentation ethic, which, as far as I can tell, is truly what Rothbard called it: a dazzling breakthrough.
I received my books tonight and finished Hoppe's 23 page pamphlet just minutes before the writing of this review. I think you really ought to give this pamphlet a read, because it is truly elucidating. I won't go into detail; just know that Hoppe is a gifted, persuasive writer and you will feel so grateful for the things he has brought to your attention. I know I am.
Good night! Buy Hoppe!
