Every study that I know show that the dematerialization of economy will lead to a degrowth [1]. Moreover there are many non material things that we need but the majority used to be free. Having time with friends and family for instance. Do we need to turn our relations into a commodity only to achieve growth? Why are we so obsessed with growth that we are willing to exploit ourselves and the planet in order to achieve it?
