Why resort to absurd matter replicator analogies, when there are truck loads of far more relevent historical analogies available. You are writing as though music sharing was a completely new class of problem (and therefore needs new measures to regulate or eliminate it), when in fact it's merely a re-run of an old, old problem.
Exactly the same problem was faced by sheet music publishers when photocopiers became common, a common sense solution was found. The music industry has already faced the same situation with tape recorders, there was no need to panic. The film industry should have learned their lesson over VCRs, but quite obviously they're just too mindless to do so.
The fact is there is absolutely no evidence whatsoever that music copying by consumers has harmed recording industry profits. in fact their profits rose significantly during the Napster years, and have declined since the demise of the service. Hardly compelling evidence of their claims.
Nobody is saying that mass copying and organised redistribution of copyrighted works isn't a problem, just that harrassing consumers and removing traditional fair use behaviour hasn't solved similar problems in the past and is unlikely to do so now. Please address the point being made, and not a different point that's easier for you to attack.
