This is the audio version of the essay “No Treason: The Constitution of No Authority” (1867) by Lysander Spooner. I listened to it last night and can highly recommend it. Murray N. Rothbard considered this essay “the greatest case for anarchist political philosophy ever written.” Will be worth the 2 hours of your time. If you’d rather read it, you can download a PDF on Archive.org. There’s also audio available on Mises.org.
