Most friendships in reality are built on convenience, routine, or proximity, not some deep meaningful bond. Once the shared environment disappears, so does the relationship. A big part of what people call “friendship” is just structured social habit — people to talk to so life feels less empty or repetitive. In that sense, having friends isn’t automatically valuable. It depends entirely on whether the connection actually adds anything to your life or just fills silence. Some people are better off alone than surrounded by low-quality connections they feel obligated to maintain.
To me it seems you’re implying that temporary and conditional equals to shallow and meaningless. I do not think that is the case. In the end human life is temporary, so absolutely all relationships will end one way or another, that is an inescapable fact. It doesn’t make them automatically lack depth and meaning. They can still give you experiences of genuine connection, exchange of ideas and chances for reflection.
Having people to talk to so life feels less empty or repetitive, to me, is worth the investment it takes to maintain some friendships/relationships. Filling the silence can sometimes be enough. And I like the silence. Just not all the time.
Some people have chosen a different path and I’m sure that hermit life can actually be deeply fulfilling and meaningful. However such people don’t usually go around social media looking to contact other people, so I doubt you are such a person, but obviously I don’t know.
