Hugh Nibley points out the line of argument used in 1 Nephi 7:7: "They were desirous to return unto the land of Jerusalem." Notice, the lands of their inheritance were not in the city of Jerusalem but far down where they went to get their property for Laban. The "land of Jerusalem" is a term that was used anciently.
