What part of copyright allows you to sell a used book, cd, or dvd as you wish?

The sold copy should not be the replica.

Explanation:

The transfer of the copyrighted work does not include the movement of the physical storage medium like CD, DVD, and paper. Instead making a replica of them is not allowed as well as ill-legal distribution. The copyright allows one to sell the used book, cd, dvd and the matter should not be the replica of the original matter as the replica is infringement of the copyright.
