They're just two different ways of approaching risk. The so-called "doers" are taking on much more up-front risk than this type of grassroots attempt. Ultimately the goal is the same.
I'm not sure that's true. "Doers" by definition, are putting their effort solely into providing food for a populace. If a company becomes necessary to do that, so be it, but it's an obstacle to be overcome. "Planners" (in this case, at least) are focused on building an organization which meets the 7 + 1 coop goals linked at the end of the article and will, when complete, allow the provision of food to a populace. One is a bottom-up approach, the other is top-down. They share a goal, but they have different aims.
