That's absolutely not true at all, IMO.
Not all art is created for the purpose of creative expression. Much of the labor performed by artists is better classified as "communication". It conveys information or ideas for non-creative purposes.
Technical manuals have meaning without creative intent. The logo for your local pizza place has meaning without creative intent. Even things like application interface design can have meaning without creative intent (creativity in UI is actually a rare thing to need; mostly we're building on established paradigms people are comfortable with. Sometimes creativity is needed and good but not always)
So I fundamentally disagree with your premise as a rule. The type of art people are passionate about is creative art. But not all art needs to be creative.
