This (and other explanations in this thread, like "might fly around") seems to tackle the question from the wrong side, imo. It seems these reasons are made up by rational minds, trying to understand the ban. Like results from "Why the heck is this prohibited again?" pondering, but completely based on speculation. So unless we can get some facts to back up these claims, I doubt that these replies help the OP. It sounds more like "Been there, thought about it, this is what I/my coworkers could come up with to explain this mistery"?
