I agree with that. My main concern is not people who make unauthorized copies of music and then later buy copies; I personally think that's great, and ought to be somehow legal. I am concerned about people who make unauthorized copies of music with no intention of ever paying for it and just flat out don't care because they don't feel it's worth paying for, even though they clearly see it as something of value, since they listen to it.
The huge difficulty is, how can you reliably discern between these classes of unauthorized copying?
