The only thing that ties you to your physical goods is the information of your ownership of them in the first place. If I have a device capable of cloning that information and taking that which you claim to own simpl because it is possible, you would would have little recourse in taking it back. Information is essentially everything. Your title to your car is a piece of information that prevents me from just taking it from you and saying its mine, or that it is better for the public if I use your car.

If you read my long post instead of tl;dr'ing you would see.
