"In both cases someone enjoyed the fruits of your labor without compensating you for it."What labour? I didn't expend any labour at all making a copy of that program. Why should I be compensated? Why should I even know?
Your thesis relies upon an arbitrary, and I would say quite baseless, link between a piece of information of whatever form and some kind of implied reward for its originator. But this system breaks down completely when copies can be made at almost zero cost. The labour and hence reward does not and should not multiply automatically in proportion to the number of copies in existence. How could it?
As an example of how arbitrary and harmful your belief system is, take, say, mathematical theorems. As you know, we have many mathematicians around the world. They work, very hard, on extending mathematical knowledge. And yet, unlike a movie or a song, a mathematical theorem is not copy-protectable.
You use any number of those theorems every day, if not directly then in the products in your life. No mathematicians are being compensated for your use of their labours. No-one suggests that unless mathematics are copy protected (life plus 75), that people will stop doing maths. Why isn't that protected too? Especially considering mathematics is rather more important for our society than a few movies?
Information in and of itself has no "reward" value, zip, zero. It may, of course, have immense "use to society" value - hence the importance of its sharing, as wide as possible and as easily as possible.
More along the "examine your beliefs" theme: why is there such a discrepancy between patents and copyrights? I happen to believe in patents, if done properly. They encourage innovation in manufacturing and technology. They are of immense importance. And yet patents are generally 20 years.
Why so short? To encourage innovation, of course.
Why are copyrights so long? To encourage innovation, of course.
Do you detect any cognitive dissonance in the two above statements?
Right, I'll stop before I go any further off along this tangent : )
