What I've been observing, though, is people acting as if the software is free because copying is practically free. This happens all the time and nobody even thinks about it. Friends share programs, music, movies, pictures, documents and all kinds of data among themselves and they may not even realize the fact they're infringing copyright. I see my colleagues sending each other copyrighted scientific articles via messaging applications every week. Nobody really thinks about some journal's copyright, it's just "those people need this file and I have it, so I'll send it to them". Companies have been trying in vain to police this behavior for years. I don't think they're ever going to succeed. I think that's a sign this system is incompatible with current technology. What good is a law if you can't enforce it?
>It's like saying "gasoline should be free because it costs next to nothing to run the pump motor at the gas station".
I don't think this is the same thing. A more apt comparison to software would be "gasoline should be free because the pump is magical and can somehow duplicate existing gasoline, creating new matter in the process, and the cost is so infinitesimal we don't have coins worthless enough to pay for it unless we purchase a whole tanker's worth of fuel". I'm willing to bet that such a magical pump would drastically change how people perceive the value of gasoline. Even though creating that first volume of gasoline required a substantial amount of money, the magical pump can simply duplicate it endlessly.
