Top answer

Because demonstratives aren't used in tags; they take the same tags as 'be' because they refer to some noun. In your first sentence, 'there' is existential—it has no locational meaning but simply marks the space of the real subject, 'book', and is repeated in the tag. That [blue thing] is a book, isn't it?
