For better or worse, these all predate the modern conventions of intellectual property.
You are wildly incorrect. Intellectual property rights were invented by ~500BC by Greek colonists in Sybaris (Italy) predating the invention of movable type and the use of gunpowder in warfare by well over a millennia.
Wildly? Anyone practiced these for successive thousands of years elsewhere?
Just my poor attempt at humor. I should have said, "surprisingly." Nice catch.
