Humans act. Human parasites are human. They act, too.
By definition, human parasites are those humans which hamper voluntary exchanges between humans for their own benefit. The “state” can only be eliminated to the extent that human parasites can be eliminated from the human population. AE does prove that humanity without human parasites, i.e. humanity in which voluntary exchanges are unhampered, is one which creates most peace, wealth, and prosperity, but AE can not prove the non-existence of human parasites. Empirically and historically, they’ve always been among us.
So the question is not whether one prefers a world with human parasites to a world without them. The question is rather how does the non-parasitic (productive) portion of humanity best deal with its parasitic counterpart. I don’t know the answer to that question. Perhaps, the humanity is still experimenting toward finding this answer in the laboratory of history.
