Actually, they aren't. They're what's left of corn tortillas after the industrial frying process stripped anything that could be considered nutrients (hyperbole, of course), with a little salt added for flavor. Now you just have a calorie dense but non-nutritious glorified salt lick.
It's hardly food, and if you don't think so, try living on nothing but Doritos for a week and see how that works out for you. Potatoes may not be much more than starch and fiber, but I could live off those for any length of time because they are food.
The difference is that the fried corn tortillas that I make fresh actually retain the majority of their innate nutrients and could sustain me for a week, more even.
Look, I get that not treating snacks like staple foods is a good idea overall, and we're probably not going to see eye to eye on this, but it's not clear to me that the profile of "innate nutrients" is actually different in Doritos. They might have that taint of being a mass-produced snack, but they start with corn just like your homemade tortillas. Unless I'm missing something, the industrial frying, packaging, and seasoning is not stripping nutrients, intentionally or unintentionally.
It's a relatively simple product, as packaged snacks go.
