I was thinking along the same lines, you need professional editing for professional results that seem like they were written by thoughtful individuals.
No differently than any other "content" which is churned out rapidly and mindlessly over the centuries.
To make it appeal to actual readers, somebody has to take these sketchy drafts and refine them with a human touch.
If you want to appeal to thoughtful individuals.
Usually if it takes less time to put something into words than it takes for a person to read those words, something is wrong and people will be able to tell that there has been no professional treatment.
