Just because you can touch it doesn’t mean it’s real;
Just because it’s immaterial doesn’t mean it’s a mirage.

This is just as true for feelings, emotions and our own consciousness as it is for NFT’s and other forms of digital art. The NFT and human consciousness are running along a parallel experience. Think about the power of memories, of plans you have for the future, they hold a gravity to them and yet they only exist inside our own heads. As the wise words of Dumbledore to Harry goes:

“Tell me one last thing,” said Harry. “Is this real? Or has this been happening inside my head?”

Dumbledore beamed at him, and his voice sounded loud and strong in Harry’s ears even though the bright mist was descending again, obscuring his figure.

“Of course it is happening inside your head, Harry, but why on earth should that mean that it is not real?”
