Once the info is free in the analog state, it can always be recaptured. There is, however, no substitute for the live performance. Arguing as to the quality of the copy (of a live performance) is analogous (and just as futile) to arguing as to how many angels can dance on the head of a pin. Digital copies vs. scratched analog copies is really not the issue. A copy is a copy and NOT the original performance. It is a memory of the live performance.
