"Reality has a well-known liberal bias" --Stephen Colbert
Social primates generally have collective senses of justice (if my friend gets a grape I should get a grape too). Even on a single-cell level self-sacrifice for the collective (slime moulds).
Of course, its totally possible to argue that these traits could be Libertarian traits too. Aren't we the only creatures on earth with government?
Also, collective justice isn't exactly something you want to appeal to in general. The mob might lynch you for being too annoying, for instance.
I wouldn't consider family or tribal preferences to be particularly cogent with the philosophy of Libertarianism, for instance.
A lot of Trump supporters are that way. They want endless liberty and greatness for American, but if you aren't American you can fuck right off -- you're lucky we don't just come take your country over.
