[Question] If digital goods in virtual worlds increase GDP, do we actually become richer?

Noah Smith, in this article, argues that the Metaverse could enable economic growth to increase a lot and sharply decouple itself from real-world resource usage. By creating markets in which we buy and sell immaterial things, world GDP would grow.

He also says, rightly, that GDP correlates with the well-being of a nation.

But there’s a non-stated point: would creating huge markets in the Metaverse for buying and selling digital goods make us actually richer? What I mean is this: suppose that, thanks to the Metaverse, huge virtual economies get created and people get real money out of stuff they sell in these economies. But suppose that e.g., agricultural production output doesn’t go up much. Does that mean that we’re simply going to pay more for groceries, without being able to afford more of them? The more general question is: would real-world stuff simply get a lot more expensive, and so our well-being doesn’t really increase besides us being able to afford digital goods and having richer virtual lives? (This must count for something, but I’m more interested in whether virtual economies somehow would trickle to the real economy and make us able to afford more physical stuff.)

This is not a leading question, I genuinely can’t tell what’s the right answer, because I don’t feel confident enough in my knowledge of economics. Perhaps a way to rephrase is: what dominates here, inflation or virtual GDP growth? Is that even the right way of looking at the problem?
