The problem I have with the hardcore libertarians (as exhibited in this thread: darkllord700 and Knalus) is that the "Less government!" cries are seen as some sort of fix-all solution. It begins and ends with "Just get the god damn gummint off my back in every way possible!" for these people.
Like with anything, simple single-statement solutions aren't solutions at all. Each issue or facet of society usually demands careful consideration and unique solutions and those solutions need to be revisted. Sometimes it ends up as less government intervention, different form of government intervention or sometimes more government intervention.
If your only tool is a hammer ("less government!"), every problem starts to look like a nail.
