Copyrights, patents and trademarks all share a single unifying assumption: ideas are things that can be owned. Since I disagree with that assumption, it makes sense to speak about "disagreeing with intellectual property" if IP is just a synonym for "a legal framework that uses violence to support laws that allow ideas to be owned."

That's an interesting piece, thanks for sharing. I think from the perspective of "what existing pieces of culture can I use to create something new" IP is actually a useful bucket. From the perspective of people who have already created or are consuming that piece of culture, I agree that combining trademark with copyright and patents is not useful.
