Communication isn't all or nothing. The more expressive power you have, the wider the scope of ideas you can communicate. It may be minimally sufficient to be able to communicate "me hungry" or "that crazy", but more is probably still better.

To add to this, expressive power also makes it possible to communicate nuance and discuss biases and fallacies.
