You say Libertarians are focused on "unjust property laws", but sadly most Libertarians these days seem to be royal libertarians, supporting land as private property where the owner is 100% sovereign and are opposed to such things as inheritance tax on land. If you agree with the arguments of this article (I do), this is fundamentally unjust property law. People who don't own land are at the mercy of land owners and so are not free. The Mathew Effect ensures that land ownership becomes more and more concentrated, contributing greatly (if not mostly) to the extremely poor distribution of wealth that we see today. What are your opinions of the article's arguments?
