I believe the meta-verse is going to be a very good example of the infinite game, or the age of abundance as taskmaster often calls it.
As you will be able to earn from everything and anything you do in the decentralized metaverse, the only factor that remains limited is attention. There's a limited amount of time for a human being in which they can be focused and attentive to something.
Other than that it will be the exchange of any service/product for spending time and/or sharing information.
Amidst all of that people will still want to have things that are special, unique, collectible, luxurious etc.
And the community does not need to be very big to be successful in providing value for its members. Cubdefi is a great example for me how a relatively small community can create great value for its members.
Also, look at what opensource software did create alongside the Microsoft's of this world. I think there might be a Facebook controlled metaverse, but alongside it I hope there will be a decentralized one that is being worked and expanded on in every possible direction. Not controlled by anyone, totally unpredictable and disrupting any industry.
We’ll have to see what happens as these things are very hard to predict
