If somebody steals your car, he has actually made you worse off than you were before; you no longer have your car!
If somebody steals a copy of the song you recorded, you are not any worse off than you were before; you are simply denied the opportunity to have been made better off.
Personally, I see a moral difference between the two. Somebody who maliciously reduces my stash is much higher on my shit list than somebody who (even maliciously) fails to add to my stash by getting something I produced that is infinitely replicable without paying for it.
I feel like you said it yourself: "Intellectual Property is the morally valid exclusive use of something non-physical"
That concept doesn't make a lick of sense to me. The physical realm is bound by scarcity, but non-physical ones are not. There's an infinite amount of love, of joy, of ideas, of music, of speech, of spiritual enlightenment… it goes on and on. To me it just seems selfish and greedy to attempt to enforce exclusive use of something that there's no actual barrier to sharing with all the world. It would be like building a sealed bubble around a town and then charging everybody under the bubble for air when dismantling the bubble would result in everybody being able to breathe as much as they liked for free.
