The actual use of it is an escape to the reality. There are people that have chosen to stay in the Metaverse rather than to commit their lives outside of it, in the real world.
From what I've read, there are some ways of surviving there and actual lives like you're really going to work inside of it. And I think we're going to that point someday that our virtual lives will have means of living and earning, working and socializing just like what we do in real life.
