Your car is a singular object that can't be duplicated - I don't think that's a fair analogy.  A better analogy would be something like: someone stole my song when they downloaded an mp3, then selling it, me catching them, and forcing them to remove it.

It happens, right or wrong, and digital content rights are a huge struggle for society right now. You see the entertainment industry fighting it as hard as they can right now.  The real question is what happens when steemit gets a DCMA takedown notice for a post in the blockchain? How does that get removed?
