I mean, I could claim anything upset me enough to cause me to lose sleep, couldn't I? I'm feeling pretty upset right now that someone could say something like what you've said, in fact. I might not be able to sleep knowing there are folks who feel that way.
And, that is effectively what these laws are about; the industrial agriculture industry wants to be completely free from criticism and free from being seen committing crimes. They already have the protection of the law when it comes to breaking and entering, trespassing, etc. They want law that goes beyond that and shields them from any criticism. Which is not a right we in the US have; we can sue for libel, but we cannot demand that people not say true things about us that are unflattering or upsetting to us.
These environments, or disrupting their operations because you're trying to get a sweet shot, can be legitimately dangerous. Discouraging people from trespassing in search of publicity could certainly constitute a rational basis for such a law.
It's a neat trick to ask what possible justification there could be and then downvote the explanation.
