Upvoted for a great analysis and discussion item. I don't know the best solution with curation rewards; everyone seems to have a different view. I really like that you are focusing on creating demand. We need to include a measure of engagement, perhaps via reputation scores, and I think demand means engagement (user retention and activity on the site) and increasing users (bringing new people to the site). We should keep those in mind as we determine how to allocate money most effectively.
