Data Storage Marketplace to answer your question on use case outside of bitcoin. Of course that relies on several assumptions that remain to be seen, first that the user-experience will be acceptable comparative to centralized solutions, 2nd that the cost will be cheaper. But again that is really the answer for any/most use-cases of blockchain, which is really just a socialized way through inflation (production of new tokens) for confirming data to be true (in this case that data is stored in a reliable/accessible manner). So as long as the application itself can meet that standard, there exists financial opportunity.
