I totally lost my huge post
I'll sum it up:
1. used sale = lost sale is a fallacy (just as pirated game = lost sale).
2. buying new cars is actually harsher than buying used, I would say. You pay quite a premium for buying new in cars.
3. movies and books are more similar to games than cars, and in movies you naturally expect to pay a premium for seeing it right when it is released. Old movies even show for free in TV (where "free" is really "ad supported"). For used games you also need to wait a bit to play them, like in books (the respective industries also try to control lending and re-selling when they can, of course).
4. buying used is probably more common than pooling together, I agree. But many brothers and friends effectively pool together without doing it explicitly, by lending them (and I'm sure developers also want to curb that).
5. The gamer that buys used may have instead less games paid full price, but in the absence of the used market he may also instead have 0 games paid full price as he may find the value for money to make it not worth it - he may go to other entertainment options that do not give ANYTHING to the industry (buying used gives something, despite what the industry likes to claim). There is no shortage of free games.
6. The total impact in industry is very hard to establish. For it to be a negative impact the total amount they take with the current situation would be smaller than the scenario where the used game market does not exist. I believe that for that to occur you need many more "time limited players" than you have "funds limited players" and I don't think that is the case. "Funds limited players" are not going to give more money to the industry in the absence of the used game market - they may play less games, or they may even decide to give up commercial games. "Time limited players" might buy new instead of used, but if they are time limited (making them less likely to "waste time" with lower quality free games, for example) they may already be buying their games new and not re-selling them currently. So... Maybe the used game market helps the industry despite what the industry claims / believes.
7. The industry (at least segments of it) are very worried about iPhone games. Wonder why? Perhaps it is because they think/know that that commercial games are a tad overpriced. Used game market cuts that a bit so maybe it is helping them without them knowing. Perhaps the industry should spend less money in cutting edge graphics, refine gameplay and sell the games at lower prices (like many indie devs and digital only games are doing). You can't even say "it doesn't sell" at the moment because obviously iPhone games can sell a lot of units and they do not have cutting edge graphics. But I'm a biased retro gamer of course.
