Your car analogies are *idiotic*. The actual analogy would be a device that you can point at any car, which creates an exact copy(minus any personal items) back in your garage. It doesn't affect the original owner of the car, aside from resale value, which was never guaranteed. The device would obviously be a miraculous boon in many ways, and the car manufacturers would find themselves in the exact same position as the **AAs and be falling over themselves to push for ever-stronger penalties and more heavy-handed preventative measures against people copying their designs, and would call the scanning "stealing" (and it would still be a misnomer). And yes, their old business model would be rendered rather obsolete. Independant groups would undoubtably arise to design their own cars which could be freely copied, although without the money and expertise of the large manufacturers behind them, most people would probably still perfer copies of the big names, at least initially. Things like custom-designed cars for each person and susbcription services where you can go into a showroom to scan a new car each month, or have the car dealers' scanners deliver new cars automatically, would undoubtably become a larger part of the business of the car companies that survived the transition.
(I should note I'm ignoring negative exernalities [increased pollution, etc.] for the purposes of this analogy, as digital data transfers are a bit different from physical objects in that sense. You could actually make a decent connection between increased traffic congestion due to free cars and increased bandwidth usage due to piracy, though. Still a net positive on that front in my opinion, especially as things like legal streaming services are making more bandwidth necessary anyway)
