The reason "Intellectual Property" is bad is because it is a term that (probably intentionally) conflates so many almost completely unrelated issues
If we're being trained to think that copyright, patents, trademarks, etc. are all the same thing, then you can make an argument that works for a small-time artist's creative works, and then do a switcheroo and suddenly we're talking about drug patents
THAT is what I mean when I say that "Intellectual Property" isn't real or needs to die
