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.
The trust system doesn't prevent anyone from fending for themselves and doing their own research. DT is optional. Trust lists are optional. If someone wants to go full Amish they can just wipe their trust list and have at it.
Except if you want to build a reputation for trade under this system, then you are directly penalized for not participating in it by having positive trust ratings left for you being less visible.
