I have pirated things in the past, will probably pirate things in the future. My intent is not to say how awful piracy is or to support the idea of IP rights, it's to help make everyone understand that they're using the word "owning" inaccurately when talking about licensed IP.
You do not own that film you "bought a DVD of."
When talking about IP, "buying" and "owning" are just not the same thing, and they never have been.
