Thanks for the comments.
Yes, it lets everyone sell articles on the platform. Of course, it's also possible to publish articles without a price (I think free posts will always be much more than paid ones).
It's true that there are not so interesting articles that are worth to pay on Literatus at the moment. It's a brand new site. Hope there will be greats authors and thousands of high quality priced posts in the future. I think readers don't stay back themselves from paying a little amount of money to read a good article in that case.
Authors already try to earn money by sellings their writings on different platforms like Leanpub, Tuts+ etc. So, I think there is a room for this model.
The problem I see here is the author has no way to monetize their content without making their articles "paid", and in that order their only way to earn is to build up an audience for themselves which I think will take a long time especially if the site itself has not a lot of users by now. Unlike Youtube, Steemit, and other money earning ways for content makers they earn without making their content paid at the same time their followers gets what they want without paying anything. You have a good thing going on here but I don't think it would work for you and your authors.
