I think they're talking about utensils & storage containers (no plastics) - pots and pans (non-reactive, like glass, no nonstick coatings), no silicon spray, plastics, or aluminum foil) - all like that. Some folks are hinky about microwaved food, I suppose that too. Wood fire grill instead of gas.
And yes, all ingredients are considered food, spices aren't that difficult to get organic. As for salt, it's elemental, my dear. Organic salt would be without additives, sea or land mined.
Organic has long been the hype for everything - but sometimes there IS a method to the madness. It's really just a way to avoid adulterated food.
Then there's the raw food crowd - they "cook" fish in citrus juice, heat is verboden, as part of their organic style.
So, not a dumb question - it's just loosey goosey and depends on what you can see for yourself pretty much.
