What? Her landing in "utopia" is not nearly close to the ending, nor is it magical: at all times the heroine has the option to voluntarily join this utopia and she consciously chooses to remain in the "outside world" to fight its demise. And she doesn't magically crash there, the actual process of her getting there is narrated in what is probably a good 30 pages. Using an analogy from a false representation of the plot to imply that the author intentionally recognizes flaws with her philosophy is definitely not the most objective review of this book, to put it nicely. Have you even read the book?
