Thinking About Liberterians

I dont understand how Liberterians build buildings. A building cannot be built without planning, capital, permits, technology, and group labor. I dont think Liberterians work well in groups. I feel that in modern society, Liberterians are people that want to live in villages and enjoy this lifestyle while completely turning their minds off to the problems of the modern world. Many of them I have met have had singular world and time perspectives. Many have failed to account for historical forces. I dont think Liberterians are their own party. I think they are offshoots of the Republican party. Whenever I see a Liberterian inside a building, I think to myself, "How could you have built this yourself asshole!"
