1. Why not have people compete to build better marketplaces for selling AND listing? If you really love the free market and the game, you should like this proposal, it incentivizes competition in more areas, leading to better and better tools at lower and lower cost.

2. 3rd parties can start incentivizing listing with their site by offering cashback for sellers, leading to lower costs for sellers, leading to them being able to list for cheaper prices, helping buyers. Net 0 effect on buyers.

3. this is the only reasonable point and I agree it should be 1% or less to the DAO.

You should take off your conspiracy theory hat and look at this from a more thoughtful and considered point of view.
