I'm sorry to interrupt you, but my time is limited, as you know. We've already seen where someone could become a character in a novel. There were several books in the “Le livre dont vous êtes le héros” series, which for that matter was not available in digital format.
Earlier, you mentioned copyright. I always draw a comparison between copyright and the situation of the builder of an apartment complex. While he may rent out the apartments, he still owns the building. Just because a tenant decides to repaint a wall doesn't mean the wall suddenly belongs to him. It's easy to find the author of the book in which we are the protagonist, whether that book exists in traditional or digital format. Copyright must be respected.
