No, you can't argue that the best medium is dirt. Just like you can't argue that the best medium is vinyl.

But you could maybe argue that there are advantages to dirt (at least a hypothetical dirt which can be used as a musical medium somehow) which you lose by going to CD or vinyl. If this hypothetical dirt managed to be constraining in such a way that it produces kinds of musical works which would not have been produced for CD, is that not an advantage?
