So for you libertarianism is a purely economic program?
Could you develop about the monopoly of violence? I don't remember
Libertarian being vocal against private security and prison.
Like I mentioned back on page 2 or so, Libertarianism is a philosophy from which a variety of different methods and ideas can be derived. The basic premise is that individual liberty > group desire or benefit. But that can be applied in many ways.
The core value is the same, but not all libertarians would apply that value in the same way.
Kind of like how ten men voting to rape one girl is democratic in principal, but very few people would seriously attempt to apply the idea that way. If the one girl rejects the vote of the ten men and doesn't submit, she is rejecting democracy and embracing a libertarian idea that her liberty is more important than the preference of the majority. Similarly if one person has food and ten people are starving, if the person with food refuses to let the others have any, and the other ten choose to allow themselves to starve to death rather than take the food by force, they're also acting in harmony with the libertarian ideal. Whereas if the person with food wants to keep it...but willingly accepts the vote of the majority and gives out the food so that everyone lives, he would be acting in harmony with the democratic ideal.
It's easy to come up with scenarios in which either philosophy looks good, or looks bad, but I think understanding the core concepts is more valuable.
