The advice you read is actually “eat fat to satiety,” not “stuff as much fat down your gullet as you possibly can.” Fat is not a magic keto substance, merely a food that we can eat without raising our insulin more than is necessary for survival.
But yes, unless the fat is going to interfere with the texture or taste, why worry about it? It tastes lovely, and there is no reason to fear it. But sixty years of “fat is going to kill you” and “artery-clogging saturated fat” do leave their mark, and we don’t always realise just how deeply we have absorbed the fear of fat, even though we now know it is bogus.
It’s worth remembering that the American Heart Association only became a big deal in the late 1940’s, after the makers of Crisco gave the organisation a very large donation. The AHA has been promoting seed oils and margarine in place of butter, lard, etc. ever since, not because of science, but out of gratitude for the money.
