I don't think anyone is saying get rid of copyright, but there certainly are a number of people who believe music should be available in digital form, for free (i.e. since I cannot but it without DRM than I am justified getting it from a torrent, etc.). Whether that is right or not, it certainly seems to be part of our current online culture.

Copyright law should already protect "copies" of these things, and really has no regard to profit (how you profit from your copyright is up to you).
