I just realized I failed to make an important point. The reason for my first reply was to cast doubt on your argument (although you neatly tried to cast the burden on me). It seems to me that, in the end, the question must be answered empirically (as every interesting question must). We have a tremendous amount of experience with government. It is up to you and people of like mind to *show* the rest of us that an ungoverned society of significant size can truly function more effectively than a governed one. I for one would welcome the experiment.
It's been done multiple times in history, including Penn's colony (where I now reside). Since the experiment can't be set up at will--Kennedy would send goons to get us--we have little choice but to rely on rational arguments.
However, humans are insufficiently evolved herd animals; I do consider it unlikely that the experiement could be tried or, if tried, could work. Humans often become terrifiied if they don't know who's been designated to do their thinking for them.
