You'd think that, but that's part of the point and magic, and it does not necessarily add up to that point of "leave us both more stressed than ever".
It still adds up to increasing connection, not decreasing it. The caveat is that the whole leaving room for the other person too is vital, it can't be overwhelmingly one sided, good or ill.
The human condition includes depressive shit too, and no one is unique in capacity for suffering, only details. That's still something to bond over.
You're only thinking of the manipulators and those who ~~relish~~ enjoy control over others.
You imply that the time could have been better spent in service of art or the community.
I ask you then, have you thought of the clerks? The assistants? Art? What of the writers?
Language can be used to control or manipulate yes. But before those purposes came, came the need for it to first exist, as a tool to forge connection.
To describe the sunset, give voice to the grief, and exclaim the joyous cry.
