go ask in the ham radio thread; i bet those guys can tell you. I'd guess that the original ones were so crude with the cat's whisker diode that getting one to work was hard enough, and getting four to conduct was either too much of a pain, impossible, or didn't help. My understanding is that they do use capacitors in some crystal radios, but it seems to be part of the tuner, and not just an audio smoother
