If I went to Shutterstock and bought a copy of "Family Picnic #466532", that purchase only grants me a non-watermark copy with free-use rights.

This means I can put it in my website with no watermark and they won't sue me for copyright infringement.

However, if I buy "Crypto Art", then what am I buying? It's obviously not the "original" so the "I own the original Stary Night and it's in my bathroom" brag surely can't apply.

It's not a "hard to get non-watermark" copy, because that's recorded on the blockchain in public view, isn't it?

And Van Gogh would make way more money licensing rights to use to multiple people rather than rights of ownership to a single person.

So what are people actually buying when they buy Crypto Art? What is the motivation to the buyer?
