I hear what you're saying, but at the same time, there's a ton of mass-produced, low-creativity art out there, where the objective is not to express oneself but to churn out products with the intent to make money. This is not just in artwork, but in other design based things like e.g. website designs as well.
There is definitely a difference between art and mass-produced art. In the beginning, we only had art as an expression of human creativity, and it's not until later that we got mass-produced art, whose only goal is to provide profits for the author(s). It'd be useful to distinguish the two in conversations like this.
