You're both wrong.  Libertarianism would be the complete lack of a trust system, everyone fending for themselves and doing their own research, caveat emptor.  A pure democracy would leave theymos as the only DT1 member.  We have 100 representatives (DT1) all with differing number of votes, from a wide variety of voters.  It's much closer to a representative democratic republic than either of you are crediting.
