That’s quite a stretch since 95% of the world population lives on 10% of the land. [1] We can also build vertically, and space is a whole new frontier that is seeing lots of interest lately. I don't see this as a serious limitation. Opportunity is endless.

Oh, I didn’t know you could stack factories on top of each other!

You literally can. Are you being facetious? What's going on with this discussion?

Try to go build your factory on top of an existing factory. I suspect someone will stop you.

Skyscrapers and multistory industrial centers with multiple tenants already exist.

But really? The thing most preventing you from starting a factory today is... because you can't find the land? Alright then.

It’s not about locating land. That’s easy. It’s about controlling the land.

Start by making things where you live right now. In fact that's how many HN users are producing value as we speak.

Finding and controlling land to expand your business is not a serious limiting issue. You have effectively infinite headroom before you need to worry that you can't own a factory on Earth because too many other factories already exist.
