For a “materialistic” person, the social contract is a bizarre “mental” product, close to alien/UFO mythologies: many people complain that they found themselves speaking of it without ever seeing it. Frustratingly, it is supposed to have been signed before being spoken of. On top of that, it was presumably sealed before being properly signed.
The existence of a need for such an agreement does not mean that it will arise. As I wrote earlier, it requires broad social agreement, and there is no reason for the privileged majority to give up anything. Because why would they? And there will be no new deal without the consent of the majority.
Legal regulations concerning axiological choices made by individuals in their private or intimate spheres, formed on the basis of the expectations and awareness of the democratic majority, are essentially deprived of legitimization and are not acceptable within the scope of prohibitions and restrictions they introduce.
