I'm not making that argument though. What I'm saying is, you can do all of those things (keeping up to date with friends, socializing, finding recipes, etc.) without social media. Indeed, without computers of any kind. The proof is that people did it for thousands of years before social media existed. If the argument is that you can do those things better with social media, my second point was that that hasn't turned out to be the case for many people, particularly when it comes to maintaining meaningful social connections.

That argument does not make sense. For "thousands years", you lived in small one room cabin with kids, grandparents and maybe even sibling there. You socialized, because there was no way to be alone.
Good luck finding people now willing to live with you that way.
No one will trade letters with you either. They expect you to communicate and socialize at places normal for contemporary society.
