Musicians have not always sold copies of anything. Recordings that can be sold are a relatively new technology (20th century). Musicians and artists worked on commissions or got paid for their performances. In fact today very few musicians make much money from selling recordings (talk to any jazz musician about it).

As far as lost revenue. When I drive a fuel efficient car that uses less gas, am I stealing? After all I am depriving the oil companies of revenues.
