On the contrary! I'm choosing my words carefully, based on their meaning.

Property and monopoly are similar, but not the same. Monopoly applies to a set of items, not a single item or group of items.

For example, you can "own" a copy of Pulp Fiction. You can watch it, you can break it, and you can sell it. What you are not allowed to do is sell a copy of the one you own. You are not allowed to do so, because Miramax LLC was granted a monopoly over the set of all Pulp Fiction copies.

You can own your house, but that is not the same as monopolizing the entire market of houses.

You can own the copyright on your book, but not all books. The latter would be a monopoly.

You don't copyright a book, you copyright what's written in it. Copyright for a novel doesn't decide who owns each printed book, it creates a monopoly over the entire market of books containing that novel. If you own the copyright to a novel, no one but you is allowed to compete in the market of books containing your novel.

Sure, they can compete in the larger overall market of all books in general, but they must avoid the segment of that market that you own a copyright to.
