I'm not concerned. Anything that can be digitized will be swapped.
. . . And anything that can be photocopied, photographed, counterfeited or knocked-off will be bartered, sold or given away; but it's still against the law.
I'm not a church-lady, really - but, I do have an interest in the music industry and copyright laws and I generally support all laws, even when I think it should be changed and I'm working towards that end. To do otherwise leads to chaos and ignorance imho. I see too many people ignoring the law, not working to change it, and too many people in denial about breaking the law.
There is a difference between counterfeiting and copying. A counterfeit makes a false claim to being original; a copy need make no such claim.
BTW, let me ask a somewhat-related question: if someone purchases a printer (as opposed to, say, leasing it), does that person have a right to refill its ink cartridges, and to make such modifications to the printer or cartridges as are necessary to make them work?
