Obviously protecting children must always be a priority
No it really doesn't have to always be. Protecting children should be balanced against harm to the rest of society. The vast majority of children will thankfully go on to live far more as non-children.
No it's not. You misrepresented the sources you provided by omitting their references to milk and dairy. Though still cashews and other nuts are not liquids, so stuff made from them does not meet your own definition.
I also doubt that nut based cheese alternatives are denser in proteins or fats than the nuts themselves. Not sure I would call them concentrated.
But the most significant difference is the presence of carbs. You can rely on cheese to not have significant quantities.
