The actual definition of what? `return` is not part of the Comonad class, while `unwrap` (alternatively called `extract`) is not part of the Monad class. No matter what your preferred way of designing abstractions, it seems a strange complaint to say "feature X is useless with abstraction Y" if you don't have a Y in the first place.

Well, okay then.

You may not find value in this way of thinking, but other software developers -- many of whom, yes, ship actual software with actual business value -- find these ideas extremely valuable in organizing their thoughts about the problem domain.

I'm open to sharing that mindset with anyone of a curious mind, but most of us aren't going to shove it down your throat. You're welcome to do what works for you.
