Clearly you have not heard of Napster or the concept of contributory infringement.
That applies to copyright, this case is about trademarks.
The original point of trademarks was to prevent deception: i.e. someone "passing off" their product as someone elses.
If there is no deception of customers, then it should be allowed.
From the point of view of the overall economy, allowing bidding on brand names promotes competition, because a legitimate competitor (i.e. selling a competitive rather than piraed product) gets a chance to pitch their product.
