I appreciate the explanation, but even then, it's multiple paragraphs for what I'm still searching for a succinct definition.

Or is it that it takes time to provide context to set up the legitimacy of their perception of value? Or are the way they are used or will be used still maturing?

I can't shake the notion it's an invented concept that has no value except that it's attached to a crypto blockchain or something, wherein the NFT "trademark/copyright/register" is now a new unique ".com" property or something?
