Believing in a "libertariain left" is like believing in an elephant hovering over your head (in normal gravity, with nothing to support it).

• Under auth-left, all power is held by the state.

• Under lib-right, all power is held by Individual Rights - including strong Property Rights, Parents Rights, Contract Rights, etc. This is only possible in a sufficiently educated high-IQ society, with an advanced market that includes non-profit organizations, "open source" investigative agencies, private defense agencies, arbitration agencies, etc.

• Under auth-right, all power is held by the state... except maybe, if you get good Pinochets in charge, they may permit some degree of Individual Rights. It's way better than auth-left, but still a matter of faith that power won't corrupt...

• Under lib-left, all power is held by magick. But in reality it's a bloodbath until either a Stalin or a Hitler takes over.
