Because most CS degrees are about computer science, not software development (or since you compare with engineering degrees, software engineering), and thus students aren't taught the latter (or only are if they pick certain classes). Same way a physicist specializing in electro-dynamics can't be expected to be a pro at designing PCBs for your electronic device.
