Another problem is that the court probably means that you can resell games for real currency. Currently you can buy games with the Steam currency, which means that reselling games is a legit method of piping out real currency from Steam.
I don't really see a problem here to be honest.
... and then Steam can offer payment via their in-store currency (with x% shaved off the top) to basically serve as an escrow intermediary. Win-win for everyone except the developers deprived of first-sales by the new resale market.
