I think that sums it up pretty well. Thanks for at least being honest about it.
That is its very purpose.
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.
Your argument is complicated by the fact that a lot of media, and especially for old out-of-print works, the copyright holder is not the person who actually created the work. At best it is a descendant family member, at worst it is a person or corporation who came into the copyright without the knowledge and consent of the artist.
U.S. of A would like to have a word with you.

The purpose of art and media is to generate revenue. People who create just for art are an insignificant minority. The main issue is that when this art does not generate revenue it is thrown away. Then it is no more art. It becomes (like) garbage.
