OK, I just read your blog article - a really enjoyable read, actually, the sentiment of which, and castigation of corporatism, I generally agree with.
That said, there are a couple areas of contention for me. I mean, I agree with the spirit of what you are saying, but the thing is you can still do what you seemingly want to do, which is--as the Greyhawk quote goes--"Now this world is to do with as you wish!"
But where I sense a bit of contradiction (although not duplicity), is that while you want everything to be free, you still want the freedom to make money off of it. In other words, you already have the kind of creative freedom that you want - you can tinker with, improve, kit-bash etc to your heart's content - up to the point of charging money for it.
So I ask you, why is that necessary? If what you really want is a kind of creative freedom--which you already have--why do you want the freedom to make money off of someone else's intellectual property?
I would suggest that you continue to write your own versions of Mystara and other D&D worlds, and then offer them for free, but if you want to get into the economic side of things, create your own world. Take your urge for creative freedom all the way and create from your own imagination. While, at the same time, working for the broader economic freedoms that you speak about.
As an aside, with regards to your "five hindrances" to the "Second Golden Age" of D&D, I think you missed one: the deluge of mediocrity that the OGL inspired. Don't get me wrong, I loved the OGL, but more in principle than in practice; by opening the door for anyone to publish, a whole truckload of mediocrity ensued, and it became increasingly difficult to wade through the chaff to get to the golden kernels.
Finally, as for your suggested actions, I like the idea of #1 but don't think it will happen, at least not in the "free for all" fashion you described - and at least not in the near future. I think we'll see something, probably somewhere between the OGL and GSL.
#2 seems even less likely, at least as long as Hasbro owns D&D. But again, maybe in some years. But we do need folks such as yourself to work for it!
Anyhow, I just want to make clear that I broadly support your endeavor and the spirit of your argument. I would just consider some flexibility, that it doesn't have to be either/or (completely free or corporate oligarchy), and that there is a path of gradual unfolding that can occur, and perhaps is occurring.
