This is an interesting angle that I had never heard before. I'm not sure that I agree with the specifics but I do know that I grew up reading and enjoying Von Mises over many years for the rigor of his thinking and for his courage in standing up for unpopular views. I will look into it.
It would seem that you are familiar with the Austrian school, but you are not up to speed on the intellectual property controversy within libertarian circles.
Well, Lugwig von Mises was a utilitarian, but not his student, Murray Rothbard.
