Since I'm lacking both the time and the inspiration to write anything worth reading, I'll instead direct you to the Liberty Cabal where Chris Snowdon is looking at the curious case of a philosopher who wants to make us free by restricting both what businesses can do and consequently what we can see and interact with. Well worth reading. And it is also persuaded me that I need to read the book Nudge, since my understanding of it is clearly at odds with what the authors intended (no doubt my view has been corrupted by paternalist politicians trying to nudge us in crude and illiberal ways...)
