I understand where he's coming from but this suggestion goes way, way to far. Abolishing all IP law leaves us not free but defenseless. In re Dave Winer's recent troubles, if there were no IP laws, suppose Conxion just decided to block everything Dave says about them, realtime? Block the e-mails, snip those chunks out of Scripting News, change any image they want, etc. Dave couldn't claim copyright infringement, couldn't claim anything because he would have no property interest. With no IP laws we are defenseless in the face of those with the power to change things without our permission.
