Heres the backside of the argument then. The only feature that is technically unique to a Auction House are Blind and Timed Bidding. When someone says they do not want an Auction House they really do mean they do not want Timed or Blind Bidding.
This whole thing is a problem with Nomenclature. If all the features besides a Timed or Blind Bidding were implemented it still wouldn't be an auction house and all those features can be implemented into the market ward.
