With all due respect to libertarians, this is why it is a doomed philosophy. People are not rational beings. They are easily manipulated and swayed—as this book makes eminently clear. The wolves will always try to feast on the sheep. Unfortunately, far too often the wolves are the ones in authority. And that is the reason the prophets of the Old Testament/Hebrew Bible spoke out against the authorities so strongly.
It might also be the reason Jesus didn't get along so well with the authorities, either. When was the last time a person in authority took the Sermon on the Mount as their modus operandi? Right.
