Natural uniformity

Where the differences among people are least-in the desire to be safe from violence and secure in their possessions, for example-there is less sacrifice of freedom in assigning to a monopoly the power to punish [exceptions]. Were the same monopoly to determine the 'best' size(s) or style(s) of shoes, the result would be mass discomfort, and were it to determine more and weightier matters the results would be even less satisfactory in terms of the differing values of individuals, however 'better' it might be in terms of the particular values of the monopoly.
