The language you use colors your reactions to the world around you - we   
could still communicate about common dangers, outside phenomena, and so   
forth, without the concepts of "I" and "you". Language would not become   
irrelevant, only different.

Remove "I" from language. Remove "you" as well, both language and   
concept. Why would one part of the universal body want to injure another   
part of the universal body? This point is why most Buddhists are   
pacifists. To approach it from another direction - is it any less loopy   
to go and cause another human suffering for money, material goods, power   
over them or any other reason?
The existence of suffering is not relieved by enlightenment - but the   
loneliness of suffering alone is.

I enjoy refining my understanding through hearing others' understandings.
