In my opinion a big barrier to the success of such systems is that newspapers often aren't primary sources. Most outsource the reporting to press agencies and (increasingly) to social media. Press agencies usually do sell individual stories with primary reporting, but not at the prices you and I can afford.
For mainstream press though, is it worth the pennies of a microtransaction to read someone's re-hashing of public records and social media posts? That is very much dependent on both the reader's personal expertise and the author's, and if they are mismatched the article becomes worthless to the reader. An article explaining what HN is would be illuminating to many, but entirely unworthy even of pennies to you and I.
