The extra cost for a rental copy is not for the disc (or tape) itself, but rather for the right to rent out the movie to consecutive users. Should the original disc/tape be lost or damaged, then the replacement for the disc/tape would be the cost of the physical media. The privilege of renting out the disc/tape transfers from the lost/damaged disc to the new disc. The number of licenses to rent discs that the rental company has is unchanged.
In a rational world, anyway.
