Sure, they can do that, which is a really cool thing. However back in 1787 the problems of being a publisher were much more severe. Ben Franklin had all kinds of issues publishing his periodicals, including such basic things like there being an extremely limited supply of paper in the US. The history of RittenhouseTown is pretty interesting if you are interested.
And can is NOT the same as SHOULD. Authors aren't necessarily interested in being publishers. It is said that the really good writers write because they MUST write. Is it reasonable public policy to force them to be publishers as well?
It think the idea is ridiculous.
