The "stairstepping" of the printed groove walls is what causes the "fire siren" background sound. It's noticeable, but not as bad as you imply. The actual music distortion is due to two causes: Lack of RIAA pre-equalisation, and lack of printer resolution (the "wiggles" in the groove walls for the higher frequencies are smaller than the printer resolution.)

The point is not that the quality is poor at the moment. Printers (and thus the quality) will improve, and their costs will drop.
