Tucker was way ahead of his time. He was (to what degree of animosity I don't know, but I imagine friendly rivalry) a competitor of the more well-known Lysander Spooner. I think they largely agreed on a lot of things, but there was a major wedge between them; Spooner was for a strong Intellectual Property regime, and Tucker rejected IP altogether. A lot of the open culture/proprietary culture arguments that we see now that have cropped up as extensions of the Open Source movement are basically rehashings of the Tucker-Spooner dialogs.

Plus ca change...
