>There is only one market that large: the global labor market.

This isn't even close to true and it's kind of the central thesis of this article.

Saudi Aramco has consistently been a $2tn company in the oil market.

Walmart is a $1tn-ish company focusing on a fraction of US retail.

It also ignores the idea that the economy is not zero sum and companies create their own market/economic value all the time.
