The thesis in the title makes no sense. There really isn't anything so special about the D&D systems that mean one person working from home couldn't come up with an artistic competitor. You don't need to spend any money on TSR books to run a campaign if there is an imaginative DM handy.
The only reason D&D is so big is that the profit lets it advertise and have a presence, so more people know about it. That is a benifit to the genre and encourages creativity.
