Nope, I'm talking about the agreement you consent to when you purchase access to media.
Mass market sales are not a public distribution, just a wide distribution. You must agree to the terms of the sale in order to access the media. You give your word you will not violate those terms, when you purchase it.
Morally speaking, either you believe someone can control their property, or you don't believe that. Sometimes that control involves letting many, but not all, people access that property. If you believe media moves out of someone's control without their consent merely through distribution, then you necessarily do not believe in ownership.
Which is fine, but there is no quasi-ownership concept. Either a person owns and thus controls something, or they do not. Besides, does private property become "public" just because millions of people go there? Does a rental car suddenly become public property once it's passed 100 renters? This concept cannot exist alongside ownership.
