Human society has had a lot of versions of "how things work" in regards to obtaining and distributing resources. As some of the work force transitions from physical, in-person employment (trading labor for pay) to increasingly virtual employment, some things are de-coupled, like high "cost of living" areas being less strongly related to "high paying employment centers."
But for employees, it's just an amplification of the previous trend towards inequality in employment that was already happening.
Another way to think about this is specialization. A few people can specialize in certain remote tasks - obviously the examples of education (for fitness, academia, etc.) - because creation is not tied to consumption, especially for digital goods and services.
The distribution of employment has always shifted over time as productivity has increased for certain types of work, and then new methods of employment has popped up as technology and entertainment and culture evolved. In a free country a couple hundred years ago, many people might work their own farm and largely sustain themselves off that work. But today a tiny slice of the population manages massive scale farms. What does everyone else do? Industries have evolved from nothing - large scale housing, transportation, etc.
To try to wrap this up, this article isn't going far enough. The goal might be to predict the future. If everything we know we need and want can be produced by a shrinking work force, what will the rest of the population do to earn their keep? Will some kind of redistribution scheme of resources arise, like socialism or universal basic income?
