If that's what you and the OP are saying, then you're conflating the codebase with the end product (program). Yes, the end user (at least in an ideal world) shouldn't need to modify the end product. That wasn't ever disputed, though. The point (if I have to use your car-modding analogy instead) is the manufacturer's engineering team very much does need to be able to evolve the design (read: source code) for future versions of the car.
