Touch encapsulates sex, love, massages, and other non-sexual touch that we have varying desires for.
Relationships encapsulates power, control, and politics along side love, humor, relating emotion, herd feelings, not feeling alone.

Maybe far future generations will decide that the human version is suboptimal and they'd rather hug, have sex with, or talk to a robot.
