I understand what you mean, but I wouldn't call "create for yourself" a fallacy, and definitely nothing to find offense over in my opinion.
There's a million reasons why someone's work isn't getting much attention, and it's virtually impossible for a random person to figure out which reasons apply on the creator's behalf. "Create for Yourself" basically covers most of them in one swoop.
Is your work simply not good enough at the moment? Well you won't improve unless you keep working at it. - Create for yourself.
Maybe there simply isn't enough of it. The more work you do, the more likely people will stumble upon it. - Create for yourself.
What if your style is too derivative? Too popular? They can get it anywhere following anyone? A great way to develop your own personalized style is to continue working on it. - Create for yourself.
Maybe your work is just too niche so that no one but you and a small pocket of people will ever enjoy it? All the more reason to create said work... For yourself.
Obviously, I can go on and on, and I'm sure there are examples where just continuing to work WON'T improve things, but to say that it's a "fallacy" implies that there is no merit to it, which there clearly is from what I can tell.
