Here's the issue. We know that due to economy of scale and domain experience, AWS will always have the lowest cost (to Amazon) for storage -- whether that's totally-reliable storage, or sorta-reliable. If there was a demand for sorta-reliable, they'd build a sorta-reliable S3 and undercut you. Then, blockchain adds inefficiency. Therefore, it's basically impossible for any blockchain solution to have a lower total cost to provide storage.
