Margaret Atwood and Radical Subjectivism

The word hand floats above your handLike a small cloud over a lake.The word hand anchorsYour hand to this table,Your hand is a warm stoneI hold between two words.

In a section of Margaret Atwood's "You Begin," she follows the mind of a child in the process of learning words, and uses it to emphasize the limits of language as a social construct. By this logic, language can be added to the left hand section of the board along with religion, friendship, love, morality, etc. Without discrediting the validity of Atwood's point, it is safe to say that language gives us the advantage of communication and advances the human connection. Without it, what would we use? Body language? That's a language too. I guess we could each evaluate the "energy" that another person gives off, but that seems a little abstract to use as a form of communication. Language is necessary for the human connection!
You can't have a system that promotes limitless individuality without losing some of the influence that people naturally have on each other. Radical subjectivism wouldn't work without the loss of human connection. Is it worth it to feel the freedom offered by the suggestion of a world without social constructs if it means you are alone? If each person has their own set of guidelines and experiences, doesn't this make us less social? Don't we already have the privacy of our own distinct minds? The vastness of the world is an attractive concept, but using every bit of the world's potential just doesn't seem feasible.
