Pre-owned games pose much of the same problem on the console market as piracy does on the PC market. The end result of both is the same: people play our games without a single bit of money ending up with the people who made the game. In the worst case, we end up paying a lot of money to keep servers online, while getting no money at all from the sale.

I find it hard to believe that he's making this argument with a straight face. When someone pirates a game then you have two copies of the game online. When someone purchases a used copy of a game then, sure, the publisher doesn't get any more money, but the servers still have the same level of traffic on them.
This is like saying that selling a used car that's still under warranty is bad for the car manufacturers because they now need to maintain the car, even though it has a new owner.
If your original price can't cover the cost of the services that you've promised to provide then clearly you need to raise your prices.
