>our entire society exists because of intellectual property Are you sure that's true? If so, in which century did it start being true?
From the beginning. Ownership is intangible. It exists only because of the collective consent to laws. The difference between ownership of a physical object and ownership of an intellectual one is a matter of conventional. It's easier to define ownership of an object that is excludable, but that's human convenience, not a physical law.
Is that why it did fall apart?
