I'm pretty sure that's exactly why PC games fell out of the used market.
Between that and the subsequent attempts to prevent this from happening, the used PC game market was essentially buried.
Steam really only continues that established trend, barring wacky cases of people selling reg codes online.
Personally, I kind of liked it when disk checks were the standard in PC DRM, but clearly it was abused by too many for it to remain effective.
Since then, used PC games more or less have no resale value.
