Totally fair. You can definitely take the stance that without knowing what a substitute is for publishers it's still worth trying to destroy them, and have faith that something will rise up to fill the void. My argument would be that you need to be careful to not underestimate the publishers, particularly Elsevier. The shift to OA hasn't yet harmed the publishers. In fact, all the major publishers are among the largest publishers of OA articles. Elsevier is full of incredibly smart people who can adapt. So if your goal is to put them out of business, you need more than just a strategy to burn their business model (although if you could figure out how to remove money entirely from the process you'd succeed I suppose).
