If an artist friend of mine sells an NFT I am going to struggle with continuing to see them as a friend, because it's morally bankrupt.
If a non-technical artist comes to you and asks for help selling an entirely phantom product to their presumably only-averagely-technically-aware fans, why would you get involved?
Anything that introduces non-technical users to crypto -- which is really the main function of NFT exchanges at this point -- is a moral hazard.
This is why I am so shocked to see Stripe involved with it.
