Interesting choice of fights
It is interesting that the copyright people still want to fight the legal basis of exhaustion. Exhaustion is not a legal issue but an economic one: nothing prevents the copyright holder from offering his works for rent only. It is just not accepted in the market and the consideration is/would be lower than for a purchase transaction. Fighting exhaustion also has the added economic disadvantage that you have to fight your customers that paid you.
On the other hand, very little is done with regard to "content aggregation", i.e. businesses that chose not to purchase a license from you but that exploit the copyright exceptions. Oh well.
