This seems to be one of those superstitions -- a related one is "guidance systems are illegal" -- that spread by word of mouth. Nobody seems to be able to point to a specific law or regulation justifying it.

I conjecture that it arises from progressive exaggeration of the "I will not launch my rocket at targets" rule found in the standard model-rocketry safety code -- which is a *custom* of the model-rocketry community, meant to steer ignorant or thoughtless model rocketeers away from doing stupid things that might bring the hobby into disrepute. (The full wording, as of the latest safety code, is "I will not launch my rocket at targets, into clouds, or near airplanes, and will not put any flammable or explosive payload in my rocket.") As far as I know, this has always been just cautious self-protection of that community, not anything imposed from outside.
