I mean this is already (kind of) the case for video.
There's no real mainstream way outside of youtube to make meaningful money with free video content.
But yes, interesting thought which does kind of make sense. The marketplace-ification of the textual web.
With google search you don't get money for creating content as people rely on summary provided by the search.
Imagine people would go to youtube and watch previews of your videos solely; or the preview is your video, but condensed and given preferential treatment.
