Values

Why do you think culture is needed? It always seemed to me that this is a set of certain rules that are absolutely unnecessary in the life of a free person. But still there are many of us and we differ from each other. Therefore, everyone has their own concept of freedom. And what is included in the concept of "freedom" and is culture. In my opinion. What is the basis for friendship, for example? Based on shared interests, values, and an understanding of what makes life enjoyable. Even this can already be called culture. Some of the topics and concerns which are relevant in the environment of your friends who allow you to feel free and realized. Perhaps culture is a lifestyle? The core of decision-making?
