I don't disagree but I do wonder if a.) discoverability is really so intractable in a decentralized environment if you're willing to throw a lot of resources towards indexing and b.) if that middle ground isn't like balancing a pendulum upside down - a very fragile equilibrium. A bunch of decentralized units might join together, or a large centralized unit might fail, pushing the pendulum to either side.
You can think of the golden age of blogs and search as an example of both. Search engines formed a centralized hub with blogs, forums, etc. forming the spokes. For a while that worked well before it was degraded by spam and consolidation of disparate forums etc. into a handful of major platforms (fueled partly be acquisitions).
