"So if they prefer lps made from corrupt digital discontnous sampled waveforms, that preference must be based upon something completely unrelated to that waveform."
The cutting head stylus cannot magically appear at the extreme displacement in one direction, disappear, and then reappear at the other extreme; it had to physically travel from point A to point B and at every physical point in between. This is why, even fed an analog signal from a digital filter, vinyl has to sound "like analog." The same goes for the playback stylus and the magnets/coils in the cartridge. The same holds true for the motion of speaker cones and your ear drums.
