Good thing I didn't make that argument :)
I'm not sure what argument you were making then.
Assuming your point isn't that you used the "factory" terminology instead of calling it "unnatural", so it's not an appeal to nature.
I'd actually be pleased to dig on the deeper part you were pointing to.
PS: the "we are not adapted" to part of your post is the crux of it in my eyes: we're not adapted to a lot of things but that doesn't make it good or bad or problematic. We're not adapted to receiving MRIs, wearing glasses or looking at imaginary landscapes in VR, and that's totally fine in my book .
If I wanted to say unnatural I would have said unnatural. I said factory.
Factories come with a mountain of lubricants, plastics, metals, agents, colorings, flavorings, etc that are poisonous. They are poisonous because we were not evolved to consume them. That's just 1 of many reasons factory made foods are bad.
> we're not adapted to a lot of things but that doesn't make it good or bad or problematic
These things would be good for you in spite of the fact that you're not adapted to it.
There are far more many things that you are not adapted to that would kill you. Your list is hilariously arguable (VR might actually be bad for you lol). My list would consist of basic inarguable things like, fish can breathe underwater naked, humans cannot, and my list would be inexhaustibly long.
