I hadn't made that claim, but I will in now that you've brought it up. Art operates as part of a discussion, the reference to and re-use of prior art is a key part of the how that happens. There are sooo many cases of copyright being used to limit the freedom of expression, that this really isn't disputable. Copyright clearly restricts speech.

No I don't, at least not in a sense that's different from the shoulders of all the people that author learned from and so on. Cultural works exist and take on roles in our cultural semiology, our memes our language without our choice. You can coose to not engage with a work, but you can't choose which works will be culturally relevant or not.
When you publish something, it becomes part of our shared culture and no-one has an inalienable right to own that. The limited rights we granted to encourage commercial creativity have already snowballed out of control and now people are blythly buying into another dramatic expansion of them.
