You keep using that word, but you haven't explained what makes it unnatural. There are people who eat insects right now, and I'm willing to bet people have been eating insects as long as there have been people. It seems more "natural" to me than drinking another aninals lactations. I don't want to eat insects, but you've offered no explanation why it is insufficient to list the ingredients (which is already required, making it different from your "organic" example).
Also, "milk" has referred to any thick, white substance for centuries now. Consider "milk of magnesia". It's the cow dairy industry that is trying to appropriate the word.
