We currently have two primary forms of government: dictatorship and democracy.
Almost everyone prefers democracies. But many, if not most, living in democracies also take major issue with the way their countries are run. The best defense of democracy is Churchill's: democracy is the worst form of Government except for all the rest.
A framework in which we can experiment with other forms of societal organization, especially one in which minimizes or eliminates externalities, has the potential to produce massive benefits if it discovers better forms of political organization.
