> Just because there is a cost to produce something does not mean that it has market value.
What shows market value is the desire for that product. The only reason that music is pirated now (when it used to be purchased) is because it's easy and without consequence. Let's say hypothetically in the future stealing a car becomes easy and without consequence (even though it's still illegal) does that mean there is no market value for cars? Of course it doesn't. It shows that people care more about saving money
If pirating music was impossible many people would return to paying for music, the only reason they don't now is because stealing it is consequence free.
The convenience argument is also (for want of a better phrase) complete and utter bullshit. I can switch to itunes right now, type in a search term, hit purchase and have the song on my hard drive (and iphone and any other device I have connected to my itunes account) within 10 seconds. Hell, I'll open my screen recording program now and record me proving this: http://www.youtube.com/watch?v=KA2wzb0-4Pg
People pirate music because it's free, consequence free (the reason they don't steal cars is consequence) and everyone spends all day every day justifying it. It's not a matter of convenience, people go to more effort pirating than they would purchasing (except for cases where the music is not available commercially, but those instances are "rare" and not a worthy consideration for the sake of this argument).
