How do you exchange something that neither of you own? Beyond bragging rights, you will need some way to establish legal ownership of something because you own the corresponding NFT. So why not sell that ownership directly without the level of indirection that is the NFT? I guess the reason is that you have decoupled ownership and the ability to sell that ownership, making it easier to speculate independently of legal domains like countries.
Really, it's just adding a level of indirection, as always :-)
