Milton Friedman on Libertarianism Part 4

I found this great (old--from February 1999) interview of "Milton Friedman on Libertarianism". Here is Part 4.

Part 4:

• What should the structure be of government under libertarianism?
• Which departments of government should be scrapped under libertarianism?
• What are the fundamental functions of government under libertarianism?

Here are links to Part 1, Part 2 and Part 3.
