Its not hard to understand. You are NOTHING like an artist.

Is your name used to promote work?

Do you have to go on promotional tours to show your face / drum up sales?

Is your work unique, no it's not. You can easily be replaced. You have a skill. Artist has talent and popularity. They could find another artist. Not easily and not with the fame and following and thus profitability of existing artist.

You seem to be conflating "artist" with "spokesmodel". Is Britney Spears the artist on her records? Only one part of many.
