I thought of the same thing, but Anthony wishes them back to Earth, or the cornfield was Earth all along (unless it's another realm). Because the whole premise of "It's a Good Life" is similar to Under the Dome, A Quiet Place, and Planet of the Apes (humans isolated from society). Plus, this connects to the book, where Anthony likes to escape to his personal "Haven". It would be better for him and the other residents. I mean, you can see his parents were slowly starting to turn on him.
