I think the real issue isn't even about earning but archive. What does it profit anyone if they earn but later their contents are deleted? I will go for archive, any day any time. It keeps history refreshed and such could also be used as educative materials. Well, if this happens and things are placed on the blockchain they're a lot of sects that won't like it because it will help keep their exposed deals permanently indelible on the internet. Criminals and corrupt politicians in Africa won't like this tech.
