That's true for many people, but people also like to show off, or to educate others. I think that recording yourself is just applying new technology to the problem. For example, Vernor Vinge wrote many of his stories on early computers. He didn't have any way to record that, but his style of annotating the text as he wrote it and thought of ideas or problems turns out to be quite interesting. He eventually shared his annotated text for A Fire Upon the Deep; you can read it at <https://3e.org/vvannot/ https://3e.org/vvannot/>. Although he didn't ever intend to publish them himself, JRR Tolkien kept extensive (but very badly organized) records of how his stories evolved over time. Christopher Tolkien later published stories from those notes, but also successive versions of the same story from different stages of it's development. "Beren and Luthien" is especially fun because you can see Tolkien's mistakes, such as characters like "the appalling Tevildo", Prince of Cats who captures Beren in the earliest surviving draft.
