The problem with Libertarians is that they do not understand that free markets and capitalism work only because of the Judeo Christian foundation of the cultures that developed those concepts. When the last traces of morality based on the designs of a Supreme Deity(Allah doesn't work) are gone a libertarian world must quickly degenerate into rule by the strongest and life in clans. Business as we know it was developed bu the Jews in the Middle Ages because their religion required them to be bound by their word. They could trust each other to do as they agreed to do. The Christians not allowing them to own land helped that to grow. Christians were able to operate that way also once they got around to it. In Asia that kind of commerce was always the prerogative of royalty and there was no trust of non royalty when out of sight. Asian cultures with some Christian background are able to do business very successfully as Westerners do. Koreans and Vietnamese Christian communities became the business class and the Buđhists adapted and adopted the ways of the Christians in business. Japan had a similar background with a sizeable Christian community in the 160s until it was suppressed but the Christians did not disappear, They hid their beliefs and became businessmen. In China the great corporations until very recently were all family enterprises and government (as weith royalty) enterprises because only relatives could be trusted. Big as those family corporations grew they had an inherent limit because they could not take on the talents of people outside of the family.
The whole world does business, more or less successfully on the Judeo Christian model and when that model fails because it has removed morality and the prospect of judgment in the next world from the business scene then it loses the reason it can exist.
