There isn't an appropriate analogy for IP based DRM because the real world doesn't behave like intellectual property. I was trying to come up with some convoluted analogy about making art on a gold plated easel that self destructs every decade and burns any canvas besides a specific size that is put on it, but just trying to formulate a physical analog hints at the absurdity of it all. Actually, wait. You buy a tractor but you can only use it on certain days of the week and it permanently shuts off after 3 years and stops working if you try to attach a snow plow to it. Except that is already the reality of John Deere products being DRM locked and not owned by the buyers.
