Crypto is already an "industry of humans". OpenSea is a centralized company, run by humans, and they sometimes need to intermediate when there are bugs or problems in their platform that causes users to lose funds. They also have to comply with the laws of whatever country they are registered in. If an OpenSea developer fat fingered their contract deployment, it would cause massive losses.
But what does that matter? The point of decentralization is not to abolish humans, services, platforms, user-experience designs. The blockchain acts as a neutral base layer, and competing services can operate on top of the same shared data. OpenSea has limited control over the NFTs being listed on it, which is why you can buy and sell the same assets on other platforms.
