so ill preface this by saying I don't really like Ordanails and i used to have the same concern. but if we pump out nothing but 4mb blocks that's about a 200gb growth in a year. If the data in those blocks where nothing but legitimate transactions (ie something without an image attached) then the 4mb block limit is too big to begin with and bitcoin is probably doomed to fail.

A 2tb ssd is pretty cheap.
