Now for an artist to copyright a song or a piece of work, for that artist to then legally make a living of is fine.

It’s not fine if you need to pay royalties to use Martin Luther King Jr’s “I have a dream speech”, because his family own the copyright to a speech that is a part of US history. They later sold those rights to EMI, and now a recording company owns the rights to the speech that encapsulates the civil rights movement, and that same recording company is patrolling the online alleys to catch the copyright infringers.
