Another thing companies miss is that the second-value is priced in to the price. If I know I can resell a thing for some value, that makes it more valuable than if I can't resell it all, and I can pay more for it. Contrary to what the companies think, they were in fact compensated for the after market value, and it's even better then they hoped, because that compensation occurred at time of first sale rather than some random time years later.

The most amusing anti-example of this was the Switch generation: $60 for a cartridge, or $60 for a digital license. Guess which is actually more valuable? Guess which you were more likely to find discounted, even if only by a marginal amount, by some store desperate to move stock out of the way?

By contrast, I'm not worried about the fact I can't resell my copy of Game X I got on Steam when I only paid $5 for it in the first place.
