The used game market hurts the developers MORE than piracy, because the people who copy illegally it isn't likelly they would buy the game anyway. BUT if a person goes to, lets say gamestop, to buy a game for $60 dollars and the store offers them the same game USED for 50$ they will usually purchase the USED copy, so its a game sale LOST for the publishers, as they don't see any money from that copy.
Nobody it's taking your option to sell your games, only that the product will work more like any other good (like cars, clothes or books) and will lose SOME value the moment you used it.
The people this policy will affect the most are those that trade in his games in a BIG store, because the store will pay even less money for the trade. But it might actually help the customer that buys used games because they will get better prices in used games, and will pay less if they don't want those features, and the developer/publisher will get some money if they do.
