I don't really see the problem with your opinion on the matter. People don't value your art when it stands alone, so you're forcing them into a situation where they'll notice and hopefully zero in on the aspects you value most. Your way of thinking is hardly any different from a person getting a job because they want money, not because that's where their heart is, or someone buying a car to show off as a bragging piece, not to get from point A to B.
So long as you're not trying to displace others' pieces and put them down maliciously, why does it matter WHY you made the story rather than WHAT you get out of it. If you meet your goal and don't have to tear down anyone along the way, I don't particularly see any issue.
For me: Summary
I want to be noticed. I want people to see the ideas I have and commiserate or empathize with the scenarios I imagine or create. They aren't necessarily new, or amazing, but I would love to be noticed for my aptitude instead of being pushed aside because it's not mainstream.
You keep doing what you do.
