Yes, but the point of blockchain tech is to enable such social contracts to be formed, and over time, strengthened. Isn't that the point of decentralized anything? You can decentralized tech all you want, but without a social contract to use it...
We can also see that many blockchain projects actually rely on more mundane social contracts like our legal system and governments with actual terms and conditions, registered companies and the like.
If you think NFTs are going to radically alter social contracts around ownership on a wider scale I've got a lovely plot on the moon to sell you.
In reality, at the moment a government had authority over those under it.
So perhaps this idea of social contracts reveal both the aim (destroying of society, hype and illusion to create communities) and the weakness (government, monopoly of violence, status quo)
