I am a limited-government libertarian.

Plato assumes somehow that government is a way in which you put unselfish and ungreedy men in charge of selfish and greedy men. But government is an institution whereby the people who have the greatest drive to get power over their fellow men, get in a position of controlling them. Look at the record of government. Where are these philosopher kings that Plato supposedly was trying to develop?

A society based on the freedom to choose is better than a society based on the principles of socialism, communism and coercion.

The same thing will happen in China that happened in Chile. Political freedom will ultimately break out of its shackles. Tiananmen Square was only the first episode. It is headed for a series of Tiananmen Squares. It cannot continue to develop privately and at the same time maintain its authoritarian character politically. It is headed for a clash. Sooner or later, one or the other will give.

Theories can be based on any assumptions, however bizarre.

Self-interest is not myopic selfishness. It is whatever it is that interests the participants, whatever they value, whatever goals they pursue. The scientist seeking to advance the frontiers of his discipline, the missionary seeking to convert infidels to the true faith, the philanthropist seeking to bring comfort to the needy - all are pursuing their interests, as they see them, as they judge them by their own values.

The true test of any scholar's work is not what his contemporaries say, but what happens to his work in the next 25 or 50 years.
