While no one wants anyone to steal a car, almost no one would mind freely cloning a car. The trouble truly is that 3d-printing hasn't gotten that good yet.
The car would be unlikely to exist if its maker had to expect free clones without compensation. So yes, people would mind.
If 3d printing was that good, stealing a car would be moot because production costs would come way down and only need to cover cost/procurement of materials and paying back the black box.
Regardless, I don't think the car is an apt metaphor here. Cars are an important utility and gatekeeping cars arguably holds society back., art is creative expression, and no one is going hungry because they didn't have $10 for the newest book.
We also have libraries already for this reason, so why not expand on that instead of relinquishing sharing of knowledge to a private corporation?
