> What is its potential? What can someone do with NFTs that they couldn't do before?
The novelty comes from the underlying protocols that back the NFT. These protocols create marketplaces that are widely available and accessible and are reliably secure and robust.
Take copyright for example. Copyright laws vary across regions and marketplace. The encoding and repudiation of these copyright laws is based on analog processes. The data related to the assets in question are stored in databases with a widely varying degree of access. Verifiability across assets or even within a single asset class varies and to varying degrees of reliability. And I'm not saying this to point out that copyright laws and the assets relying on them have failed or are not value add in many ways. The fundamental point is that the technological infrastructure underlying the use of copyright laws today has a lot to be desired when it applies to ease of use for digital media.
Networks using blockchain protocols can offer a natively digital infrastructure solution that helps extend or replicate the value offered by something like copyright law. The natively digital aspect enables broader interaction which engenders more general purpose usage which ultimately leads to new consumer models (i.e. direct artist to consumer, peer to peer, etc.).
> Owning the NFT for something does nothing more than copyright already does. You can store the digital asset on your computer with or without the NFT. You can "consume" it either way as well.
The point is not to displace copyright law)(although others may argue this I do not). The value add here is in creating a widely accessible and reliable digital mechanism for creating, expressing, and modifying ownership rights. Different, or maybe even traditional, consumption models are then built on top of this to capture this value.
To your point about gaming creators choosing to do so or not; this question is really a question about what is the value of blockchain protocol networks in the first place and how would someone like a game creator benefit or capture this value? To this point, I can only point out the potential benefits as I'll be the first to agree the nature of blockchain and its value is still being explored. My arguments above are trying to express the value as I see it.
Would be curious to hear more thoughts and criticism.
