Look at how people learn now or how they find their peer group or their life partners. Where they discuss issues. Where do they go for help.
Internet is the society. Your family is there. Your fellow villagers are there. Your sages are there. Your support network is there. And your village idiots and villains are there too.
You might not like it but that's reality and there's no comming back because internet is the best way of interacting with people thanks to its speed, memory and safety (when compared to any other form of interaction with exactly same people).
Sure, it's a tool. That doesn't mean it embodies society.
> Internet is the society. Your family is there.
No, my family is in their physical community, houses, work places, places they go for recreation, etc. That is society.
> internet is the best way of interacting with people
That is highly opinionated. And absolutely wrong if interacting with people means being able to talk in person, go somewhere together, shake hands, hug, high five, etc.
It seems you're thinking of interaction in the context of, e.g., a work environment where efficiency is of capital importance. This is one kind of interaction, yes. But there are others.
