This is an interesting real world use case for these NFTs. And I also do understand the drive behind the rich showing off their wealth by owning NFTs, much like they do with handbags or other useless crap.What's fascinating is the BAYC (Bored Ape Yacht Club) NFT's that are providing access to the most exclusive clubs in the real world.
But I'm still not sold on how transformative the metaverse will be. The thing with your example is that the NFT is only opening up a spot into a "real world" activity. So sure, use your NFTs to prove who you are and now you get to enjoy some benefits in the real world. But it all still comes down to the biological, real world.
Maybe in the metaverse, I will be able to go to a virtual mall and browse the stores and buy some stuff, but I expect that stuff to be delivered to my house because its more than likely things I want to use, or wear, or eat.
We have clearly seen the damage that Facebook has done to society, and teens specifically, with respect to their so called "online" friends. They are suffering from depression and say they don't have any real friends, even if they have thousands of "online" friends.
I'm also not sure how a virtual experience will replace the thrill of a live, in-person experience. Yes, you might enjoy doing some VR stuff and browsing parts of the world, but offer to take your girlfriend on a trip around the world in VR and see what kind of reaction you get. The chick wants to travel for real and show it all off on her IG.
Now maybe if you can convince me that men won't even need women anymore because virtual sex in the metaverse will be even better, then fine, we have a home run here, but I doubt we are anywhere close to a world where a guy will pick a humanoid sexual experience over the real thing. In fact, I will bet you that if this becomes a thing and women realize they can't use their sexuality to attract men anymore, it will all be shut down in a heartbeat since more and more women are running the world.
So although the metaverse will I'm sure grow, Facebook clearly had to pivot because they reached the end of their growth with the FB app and IG, but the metaverse is just another extension of this same concept. The metaverse might make some things easier to do, so that will catch on, but if given the choice, most will choose for real world experiences. We are after all still biological.
Now if you start implanting chips into people, or going full on Matrix style, then fine, the real world loses out. But at this point you wouldn't even need humans, nor will you have humans continue to replicate. This might all end up being deflationary for world population and that is clearly not what FB wants since this all means less users in the end.
