Which brand of libertarianism is more intellectually honest: left libertarianism or right libertarianism?

I think they are both intellectually honest to a reasonable degree of thought. I would say right intellectualism falls into the trap of monopolistic market force. Private property and finite resources makes it possible to own most of resource X. And when that happens you have control over an entire vertical supply chain unless someone figures out a way to replace or create X in a lab. I myself identify with the libertarian left, as I believe private property and wage labor to maintain it is in itself a system of bondage. But that doesn't mean I think the right is intellectually dishonest. I just disagree with them there.
