You'll notice though, that the term 'intellectual property' wasn't invented until the (roughly) mid 20th century. After which time, copyright and patent law were affixed to this construction. There was no intellectual property, prior. I would politely suggest that this piece is a post-hoc justification, based on the ignorance of this arrangement. (Because the author, like all humans, is morally ambiguous. Intellectual property was an assumption going into this piece)

Copy rights, are not property. Patents are monopoly licenses.

Maybe it’s modern nonsense.

Copyrights _are_ property. They can be sold on the market and are enforced by the state. You can _own_ a copyright.
