Nor do the video industry guys seem to appreciate that many people who buy used games are price sensitive so they won't buy new games if used games go away - they just won't buy games, period. They also seem deaf to the argument that even though the sale of a used game may not directly benefit a publisher/developer/console maker, the existence of a secondary resale market ultimately increases the sales of consoles and games because many price sensitive buyers who would otherwise be scared off from a console system if they knew they could only buy $60 new games are willing to commit because of the availability of much cheaper used games.
This is a BS argument. Those gamers are not really "price-sensitive", they're just lazy. Because if they were truly price-sensitive (from this point forward, I'm just calling them cheap), they'd know that pretty much every AAA console game can usually be found for at least $10 off, and usually $20, within a month of release from at least 1 major retailer (Best Buy, Target, Walmart, or even Amazon or Newegg for the online shoppers). And time probably isn't that big of an issue to them since you generally aren't going to find used copies of a game day 1, but even then let's say it is. Multiple retailers (Amazon, Newegg, Best Buy) have recently been offering specials that basically give you store credit for pre-ordering games from them. So you can still have your game day 1 (or close to it if you buy it online), and save an extra $10-20, which is more than you'll generally save by buying the game used from places like Gamestop.
And this anti-used game DRM can work, and is already working right now with Steam, it's just that publishers and the console manufacturers (as the owners and operators of the online infrastructure) are going to have to be willing to do something that they haven't shown that they're willing to do yet. And that's lower prices early and often. Not necessarily at launch, but shortly thereafter, and deeper than they probably would like. Be proactive in your sales, and people won't mind that they can't buy a used copy or sell the copy they have, because that copy came cheap enough that the extra couple dollars saved or the $15-20 they would have gotten back for it wouldn't really matter.
