One reason why authors should self-publish is to prevent their books from being bowdlerized by the publisher in the future. You can't predict what will cause future "morality enforcers" to faint. Self publishing also means you can publish things that the current "sensitivity readers" (i.e. censors) would never let you publish.

Of course, this isn't foolproof because your descendants or heirs might also be willing to bowdlerize your work or even take it out of print altogether. So another option would be to just release all of your copyrighted works into the public domain upon your death allowing anybody who cares to publish uncensored copies.
