I disagree that freedom is overrated. He's basically advocating the condition of becoming a sheep!
But I agree that people have willingly exchanged their freedom for security, and the result will be the loss of BOTH freedom AND security.
Why? Certainly not because freedom is overrated. It's because people have been programmed almost from birth to look to government to solve every problem in their lives. And now we've reached the point where there are legions of people who've never really experienced freedom, and don't know what they're missing.
