argument fails for two reasons. First, while technological change may have rendered Section 109(a) unsatisfactory to many contemporary observers and consumers, it has not rendered it ambiguous.

Second, amendment of the Copyright Act in line with ReDigi’s proposal is a legislative prerogative that courts are unauthorized and ill suited to attempt.
