You're forgetting that we have mechanisms in place to curate curation and farm attention toward the crap, not toward quality. It will be harder and harder to break the surface tension of this gooey gelatin wrapper we've placed over creative activity.
People will pay money for curation towards quality, probably quite a bit if the rest of the landscape is 99.99% noise. They won't pay much money for curation "toward the crap".
But that will be reputation-based, and names can be sold. Look at the brand-holding conglomerates we have today that don't make any of the original product, they just license the name out to anyone, regardless of the quality of the finished good. From mattresses to magazines, we keep seeing this. Why wouldn't we see this in curation sites?
