Also, someone may argue that they want to be a on a high saturated fat diet and it's too hard for them to achieve this without resorting to coconut oil, butter, etc. I recently saw a video of a guy who eats nothing but fruit and wants to be on a high sugar diet. When he couldn't get fruit, he started eating pure sugar by the ton. It's the same concept. I'd opt for for whole foods before empty calories and some specific macro ratio.
