No, you haven't explained the value of an NFT at all!

Look at VeeCon. Gary Vee could simply sell access to it without the NFT. What role does the NFT play there?

In the huge NFT sales, like Beeple, you don't even get that.

In fact, let's take a look at Beeple: https://en.wikipedia.org/wiki/Everydays:_the_First_5000_Days

In what possible way is this not a scam? What do you get out of this for your $59 million?

Compare and contrast with a piece of contemporary art, like Kapoor's Cloud Gate. For just $23 million, Chicago got a physical sculpture that will last for decades if not centuries and has been seen by tens of millions of people in the flesh.
