The fictional automated business may cost tens of billions of dollars to build. That means almost no one, not literally anyone, can create it. If a small group of giant conglomerates are the only companies wealthy enough to build these automated factories, then there's no competition to drive down prices, and no automatic path to a post-scarcity society. Instead, it's the dystopia ryandrake described.

So AI can build everything except the factory itself? Sounds like there's still a need for human labor.

And if the opposite is true and AI can build the factory, then it's not going to "cost tens of billions of dollars to build"; the factory will be just as cheap as the goods its producing. Literally everyone could have their own factory.

Maybe the resources, materials and land is the constraint here.

So whoever builds the first one will be able to quickly expand, buy more land and solidify their lead.

Land is likely what would cost billions in this specific scenario.

high tech "machinery" is the constraint for most capital intensive businesses

I do think in the case where a company is benefiting from the exploitation of limited natural resources (like land) that don't naturally belong to any one person, imposing a tax on that does make sense.

There was a podcast I listened to on this subject "The Plunder of the Commons" which I found really interesting. [1]

That said, we're a long ways away from reaching the point where literally not having anywhere left on the planet to build becomes your primary obstacle to starting a business.

Or the state will do it.
