I resent the idea of not being able to do secondhand sales. Could you apply that same idea to tangible goods?
It's a debate worth having. Sure, when you buy a physical item that's not a consumable, you can resell it, and that person can resell it and on and on until it falls apart from use. An intangible like a game, song, book, anything that exists primarily as information and can be easily transferred to a digital medium is a much darker thicket to wade in to. I bought the game, I have full rights to it, I can resell it as much as I want, right? That makes sense. But a game is sort of a consumable that doesn't get consumed with use. I eat an apple, I've enjoyed it, now it's gone. There's not a big market for apple cores. But if I play through a game entirely, I've enjoyed it, and for me it's basically gone. (For some games at least, obviously some games can be played almost forever, but those games you wouldn't want to resell anyway. Unless you got bored with them. Anyway, I'm trying to keep this example from getting hideously convoluted)
Once I've experienced all the content, I'm done with it. But I can then turn around and resell that game to someone else. Unlike a physical good, it will never degrade over time because it consists of digital information. So given enough time, I could resell that game to thousands of people, while the original hard working developer has only made one single sale, and is now dining in a homeless shelter.
So I can kind of see both sides of the story here, and I'm not sure which way I really fall on it. Although I'm perfectly content buying games on Steam, which allows no resales.
