So in short, don't establish an etiquette per se. Intentionally keep all options open as acceptable social choices.
I can see your point and the value within. But if I apply that back to traditional society, abandoning all etiquette and social norms would make our world a far different place. I like opening the door for my fiance and shaking the hand of someone as a greeting. I especially appreciate how it is unacceptable for people to chew food with their mouth open in restaurants. Some social rules are good and should be passed down in my opinion.
..and I choose to upvote your response as I think it is adding to the topic! :)
