The purpose of art or media is whatever the creator wants it to be. If they are an artist creating solely for the purpose of making art for be people to enjoy, then your premise is acceptable. If the artist is trying to earn money for their work, then that is their choice. If the artist wants to release their work for the world to enjoy, there are legit ways of doing that and protecting it so that other cannot prevent that free enjoyment.
I know I'm tilting at windmills with this topic on this particular website, but creating art isn't free and nobody has the right to be entertained by it just by being (either the work or the viewer) be default.
