I agree with you, but I believe this has to do with the punctuation. Emily Dickinson did not finish the sentence after “Like Stone—” therefore, she did not create the simile. Now, one could argue that “Like Stone” is how she closes “the Valves of her attention.” But if you read those lines as commands or directions, “Choose One— / “Then—close the Valves of her attention—,” what comes after “Like Stone—"?
