Saeed. Interesting article. I still find Baudrillard's value structure a compelling approach - which I can see your Importance -Worth-Usefullness are based on. However beyond that, from a design perspective, I think it's always then a matter of going back to JTBD or need which contributes to building value for customers ie. value can only be achieved if the product delivers an outcome (rational or emotional) for the user/customer.
