But, if free creation is almost nonexistent in the professional circle, is it not because it is incompatible with professionalism? Isn't free culture rightly characterized by voluntary work?

Cultural needs are a fundamental characteristic of humanity, such as the needs to eat, breathe and drink. The interest for humans in culture is instinctive, so the voluntary side of culture is inborn, inalienable and primordial. But on top of the human society characteristics are added and interwoven with a multitude of activities, such as professional, commercial and industrial ones. Sometimes these activities can have direct or collateral disastrous consequences to the domains they fit over. Starvation, air and water pollution are the grim examples related to our eating, breathing and drinking needs.
