Why does Nephi II think so much about curses? Helaman 12:18-21

In these verses, there's a lot of discussion about physical curses. Like, how stuff can be cursed to be hidden.

I think the key is that Nephi II isn't the one thinking about this. It's Mormon, the great historian/abridger of the Book of Mormon, who is inserting his commentary in these verses. And the reason why he would have cared about the physical curses is because it was his own experience, as he recounts later in Mormon 1:18-19.
