I think there is an argument to be made about validity in names. Calling something flour that is actually not at all flour, stretches the meaning of the word. I can no longer go to the grocery store and assume my flour contains grains.
I think things should be packaged properly and with proper descriptions. The same as I don't want to go to the store and buy Parmesan cheese only to find it's actually chemically altered tofu. That's not what I bought nor what I wanted.
If I wanted tofu cheese I would go buy tofu cheese.
We've become accustomed to accepting labels at face value, so I believe there is a requirement to continue that practice.
Flour comprised of mostly insects should say that, just like whole wheat flour is separated from pizza flour, as they contain different grain milling and grains.
But we should teach us that there is absolutely nothing wrong with eating insects, it's not gross. We just think it is because of cultural reasons. And those can be changed over time.
