The Paleo answer is, butter isn't. A true, strict paleo diet doesn't allow butter. Then again, a true strict paleo diet doesn't allow cooking.
My SO is big into the paleo, due to him I've read a couple of books on it, and the "science" is horribly stupid. The very first contention is that we are >9x% genetically identical to cavemen. Well, we are >97% genetically identical to mice and any other mammal you can think of, so forget it. Also, many studies are now showing that dogs aren't domesticated wolves (I really didn't just change topics, I think the dog=wolf argument is more valid than the modern human=caveman argument).
The paleo people I know all allow butter, especially if it's home made. Many also allow beer, but not oats (my SO doesn't, too his credit).
The addition of butter comes from the expansion of the "paleo" concept to "neolithic" times - when hunter/gatherers started switching to a more agricultural-like lifestyle (but wasn't there quite yet).
The good thing about the paleo diet really is the low carbness of it (I just made up a word, I'm so proud). Some strict paleo folks I know don't allow tomatoes as having too many carbs (~5 g/whole medium tomato), or green beans, or a number of veggies.
Due to my SO, I've gone somewhat paleo, but I refuse to eat all of the fat that's "allowed", including butter, and I eat fruit and any type of veggie I want, they can all stuff their paleo rules.
