You make it sound like a world with Pathfinder, and Mutants and Masterminds, and Spycraft, et.al. is a bad thing overall. You're perfect world would do away with a lot of things I like and strikes me as being rather lacking therefore. For me, the OGL has made the world, at least the gaming portion of it, a better place overall, with more opportunity, a greater gaming base, and a richness of variety.
The world is a better place when innovation occurs, but most innovation is built off of the ideas and work of others. Ideally, things like the OGL speeds up the innovation in gaming, rather than hinder it. When every company has to reinvent the wheel, so to speak, you are making a lot of unnecessary work and hindering the development of ideas.
