Where do you disagree? You point out that individuals are not statues and can shift between spending time in industry and in academia. You also point out that industry and academia are not confined by who owns the building that the people are occupying. But nobody was ever thinking that wasn't the case.

This is the first time anyone has even considered that someone could be forever stuck an academic or industry operative, or that industry can't take place in universities and academics in private businesses. Good on you for coming up with hypothetical alternatives suitable for a sci-fi thriller. You've clearly got a creative mind! But since they are only hypothetical, it is not clear what purpose they serve here or how it even could begin to relate to anything being discussed.
