That’s an extremely vague question, and presumes that any art is de facto intellectual property.
It also presumes that anyone has access to the institution that defines and enforces intellectual property.
Also, intellectual property isn’t a real thing, but you don’t want to read too many words, so you’ll have to figure that out for yourself.
In most if the modern world, copyright laws give automatic ownership of unique works of art. Legally IP is a real thing.
Is it your intention to appeal to law? Here in the states, extrajudicial detention and torture by state actors is legal. Does that make it right?
Do you think the copyright term of life + 70 years is fair to the public? Do you know how we got here?
I think there’s room for improvement on copyright laws, but that’s a far cry from the outrageous claim that intellectual property isn’t a real thing.
