This is a weak argument. Copyright collection agencies don't represent artists. Occasionally they have a few extremely high earning media personalities (notably Metalica back in the Napster days), but these kind of organisations don't represent musicians. Organisations of movie producers / TV producers like the MPAA have even less of a claim to any kind of artist representation. They're large media conglomerates, not artists unions.
