Huh? Oil is fat-dense and calorie-dense but there isn't much nutritive value in oil.

Huh-huh? Oil
is a nutrient. (Saying oil is fat-dense is like saying lumber is wood-dense). One of the nutrients we require in our diet is -- oil. Oil is 100 percent oil. 100 percent is as dense as you can get. You can't have more nutrient density, that is, you can't have more nutritive value, than
that.
Many foods are rather low in nutrient value, but are still good foods. For example raw coconut meat is about 9 percent fiber. Fiber is not a nutrient but a digestive processing aid. Plus it is about 1 percent ash. Making it only 90 percent nutrients, 90 percent nutrient-dense. Right? You use 90 percent of it and dump out the rest.

Olive oil is close to 100 percent oil.

And yes, of course I am talking about micro-nutrients not macro-nutrients (fat, protein, or carbs). Oil is 100% fat. The fat provided by oil is not a nutrient most people are lacking.
==================
The fact that many people are not lacking oil in their diet, doesn't mean that it is not a nutrient, it just means that it is not a nutrient they are lacking.
Saying that because "most" people are not lacking oil in their diet, that oil is not a nutrient, is like saying that because most lumber yards are not lacking in lumber, then lumber is not a building material.
If most lumber yards were not lacking in lumber, but their inventory of nails and screws was low, would that mean that nails and screws were building materials, but lumber was not a building material? And as a result of this inventory imbalance, if you say "building materials" should I assume you are talking about nails and screws, and aren't talking about lumber? If I go to the lumber yard and fill my pickup truck with 210 pounds of lumber and no nails and screws, is the cargo area of my pickup truck less "building-material-dense" than if I pickup 200 pounds of lumber and 10 pounds of nails and screws?
There is no reason for anyone to think that because most people are not lacking oil in their diet, that you must be talking about "micro-nutrients" when you say "nutrients." That would be like saying that because most lumber yards are not lacking in lumber, than I must be talking about nails and screws when I say building materials, and not talking about lumber. If you say nutrients I assume you mean nutrients, I don't assume that you mean macronutrients, and I don't assume that you mean micronutrients, I assume you mean nutrient in general -- both macronutrients and micronutrients.
And by the way, macronutrients are no less important in the diet than micronutrients. Just like lumber is no less important to framing a house than nails and screws.
