Something from nothing.
Conservation of mass/energy/momentum.
I think the Universe disproves your claim. You don't get productivity from nothing. You get practically anything with practically nothing when you have unlimited population growth and resources to pyramid the resource/productivity chain to ever higher levels. In that grossly unrealistic version of the world, you're right. In the real world, it breaks down, right about when we start exhausting the non-renewable resources that are fueling our current 100 year boom--unless we start pulling resources from other planets, which will turn us into a junk planet. That's the capitalist path.
Ultimately, a good life for all is a gradually rising standard for everyone without enormous imbalances that is based on increased resource efficiency as a function of better collaboration between people. Capitalism doesn't quite reach that goal because human nature includes the capable concentrating control of resources for a feeling of power and security. In other words, if capitalism were about concentrating responsibility in the hands of the most capable and rewarding them with respect instead of material gain, then it would work. Respect is a limitless resource that is extraordinarily valuable. Money isn't a limitless resource, nor are natural resources, though are current economic path would have you believe so.
Someday soon we'll have to see this.
My company builds hardware like this as well, when it makes sense. We could build you this app for a very reasonable price, *wink*.
Still think the Sun Lamp idea is funniest and quite realistic given the craze to trade food for energy and other such nonsensical ideas.
Typically, a speech broadcast to a large audience on radio and television (and considered instrumental in historic political changes and ranked as the most important speech in 20th century American history) would seem to be a prime candidate for the public domain.
Oh, OK. So if I make a song that contains scathing but accurate political commentary, and I perform it in front of a large audience, it is now in the public domain, and others can profit from its reproduction. What country do you live in, again?
It's a long process in terms of one lifetime, but extraordinarily short historically. Right now engineering is going overseas, like fabrication did decades ago. And now fabrication is coming back. One or two decades from now, the same will happen in engineering. That's what I see happening anyway. It's why I manage teams of engineers overseas. My skillset is the one they haven't gotten to yet, and when they do, I'll be running a company, and when I retire, kids in the U.S. will experience a resurgence of engineering opportunities. The issue of quality isn't an issue at all. You don't offshore your work until the quality is satisfactory, and it's inevitable that it will become satisfactory because people on both sides are highly economically motivated to make sure it becomes so.
Unless we (doom and gloom) kill off 60% of our world population when the fresh water reserves are destabilized by global warming, or aliens invade, or--wow, I sounded so stable and knowledgeable up there and now there are ALIENS EVERYWHERE!
