You're missing how commerce works. A big company can flood the market. They can use better materials and ship faster due to being entrenched.
Like, hey, you could make an iPhone but will you? You can make a movie too, but will it be as good, you can make merch, but will it be as well designed and distributed?
Even in your example, where anyone can make a copy of the book, what about the author? They could pour years and their heart and soul into a book just to make no money, is that ok?
Big companies make money of Shakespeare and the Bible all the time. I don't know why you would think they don't, they very much do.
You're also mixing monopolies with IP. You can have a monopoly with or without IP.
False. This shows a lack of knowledge around the topic. Off the top of my head I know a specific case where a small grocery store defended it's IP from Apple. In your world that wouldn't work. I mean how did JK Rowling go from a poor person with a story to a rich author. She had no money to defend her IP.
This take is just wrong. Factually.
So if you create a book or song or art piece, you shouldn't be entitled to the money that those make? They should just all be free? I mean sure, but then people will stop doing it, because of it doesn't make money people need to work to pay bills, they can't create.
