> Its a good reminder that things we think are common sense (like the government being involved in murder but not in legislating how much jewelry a girl can wear) are not necessarily so. They are very much cultural based. And these are both human cultures. What would an alien culture think is common sense?
First, I think the word "culture" is extremely loaded and ambiguous, and stereotypes great masses of individuals each with their own opinions, and to make static things that constantly change. But that said, whatever it is, it exists somehow.
IMHO this relativism argument - that it's nothing more than local 'culture' - is greatly overstated. The evidence is that individual liberty is a principle embraced by people almost every place that they have had the choice: The U.S., almost every country in Europe, Japan, China (where they have a choice - in Taiwan, in Hong Kong until very recently, and in Tienanmen Square in 1989 - they strongly advocate for it), Korea, India, almost every country in Latin America, Tunisia, Syria (where they had a choice), Benin, Botswana, etc. etc. In addition, people risk their lives to travel from repressive countries without traditions of liberty to free countries and they strongly embrace the freedom. My ancestors did. Finally, you don't see people migrating the other way.
(I don't see how speculating on unknown, non-human, intelligent lifeforms informs the discussion.)
