I think you missed the point of the article.

What you are saying is literal and descriptive. Currently corporations are always resolvable to a natural person. I think the author's point is that new technology (including bitcoin) can effectively cut out the middle-man.

Therefore, future legal (or quasi-legal) entities will be able to be structured in novel ways. Maybe it won't be a corporation by the standards we're used to. But bitcoin itself is an example of this structure - de-centralised and not "owned" or "managed" by any particular individuals.
