I don't think used games are as big of a problem for the industry as they make it out to be. It's just the easiest 'problem' for them to point to. If used IP were an issue, both the movie industry and publishing industry would've sunk years ago (and admittedly, piracy is a problem, but that doesn't mean libraries have been run out of town).
The problem with failing studios isn't with used games. Just like the problem with failing car companies isn't used cars. It's about whether the product is good enough to justify the cost. You can see this in the cost of used games. Really bad games that are resold at high frequency will be cheaper than a fast food meal. Really good games that most people hold onto are nearly as expensive as brand new games.
Really good games that were put out years ago will even get brand new sales years later. I know I bought Okami HD for $20. Same thing happens for movies: a great movie from 20 years ago gets rereleased on Blu-Ray, gets brand new sales.
To be fair, we often hold onto movies and books because we return to experience the comforting familiarity of what we love. Games often rely on novel experiences to be interesting. But if that's all a game has, then it's easy to resell it. The handful of games I would never resell don't rely on the novel (think COD's nuke moment). I want to return to them over and over again for the sheer fun of the game, not because the game has pre-rendered cut-scenes or a shocking twist. I want fun, or humor, or beauty or, if nothing else, gameplay that isn't going to play out exactly the same way every time I play (again, think of COD and the linear battles of single player).
