If you start from the same assumptions, you are gonna end up in the same place. Tabula Rasa + NAP = communism, every time.

If you believe that all people are created equal, and then observe that they do not end up equal, you are half way to communism. It must then be some violation of the NAP that has occurred to induce this inequality. Thus your libertarians are just communist.

Compare that to the other alternatives: If the Tabula Rasa is invalid, then who cares if there is inequality? If the NAP is invalid, then who cares if people end up unequal, might makes right.
