The only reason I can think of why we need to socialize with others is because we need something from them. At the doctor's office or hospital, we socialize with the doctor because we need the medical services/treatment that the doctor can provide us. At the grocery's store, we interact with the cashier because we need the cashier to check out items for us. At the bank, we interact with customer service reps because we need to them to perform banking services for us. Personally, we yearn for friends and partners to satisfy our emotional needs. Socializing has become a necessity that we can't live without, especially with the introduction of division of labor. Whether we like it or not, we have to socialize with people to get what we want.
The only way out of this is to be a hermit and live a self-subsistent lifestyle. Which means you gotta be jack of all trades. If you car breaks down, you fix it yourself. If your toilet backs up, you are your own plumber. This way, you avoid social interaction. I think it's possible to be a hermit, sever all ties with society, and still be happy; some people have done it so it's not impossible.
