Also, I pay for things I could have gotten for free all the time. Sometimes this is to reward or encourage the person providing it and then it is called a tip or gratuitity (or sometimes donation, though that evokes charity in my mind rather than voluntary payment for something provided). Sometimes it is because paying for it is just more convenient than going out of my way to get the free version.
[Edit: Slight rewording for clarity]
You're right that something can be free and abundant and still be of enormous value. I think my point is more that we should think about ways to restructure society around the sharing of valuable abundance.
Scarcity is still there. You can copy adobe photoshop, but you wouldn't be able to build it from scratch in your basement. This is the scarcity: the intelligence, creativity, and man-hours it takes to build it.
You can copy it easily for free now, but the industry will eventually change. Internet is getting faster and faster and eventually (because of the people that feel they deserve software for free), we will only have software services.
I am a developer and I don't create software applications anymore..only services. It's funny because if this wasn't the case, people could buy my apps for a flat-fee. Now they need to pay me money every month to use it.
You shouldn't try to get paid to do something that someone will do for free or cheap all day long. However, that doesn't mean you can't create value by being a musician, artist, programmer or designer. You just can't do it through the old way of scarcity. Maybe you give away the product, but the support or the t-shirt or whatever costs money.
What used to be the product and scarce is now free or almost free. New products and new forms of scarcity will pop up as people focus on creating value instead of being good at being professionals. The problem is that we've been framing our value creation in terms of "I do x" instead of "I do whatever it takes to create value. I do x, y, and z when it is needed"
Guess what. No retirement! Its a frigging ponzzi scheme! The fact that that isn't foremost on peoples mind as well as other corruptions is proof they're idiots!
If it costs me nothing to make a copy of something, then I have no incentive at all to pay money for it. It has no "value" to me. I can copy it instantly for free. And frankly, why should I pay money for it? Sure, someone had to do work to create it in the first place, but once it's created it takes on a life of its own.
And, often, the people doing the creating will do it whether I pay them or not. They do the creating because they want to. Musicians make music because they want to make music. As a programmer, many of the programs I write are ones I want to see exist. Were it not for the necessity of having money to survive, I would happily keep creating and giving away.
The necessity to make money to buy the goods and services I need to survive may be built into the current system. But as we automate more and more and produce a greater and greater surplus it's entirely possible that it could be removed from the system. It will take a change of culture, but there may come a point when we are efficient enough to produce everything we need simply by allowing people to pursue the creative endeavors that interest them and then sharing the results.
We don't have starfleet replication technology. But with digital media, 3d printers, and modern construction means we're pretty damned efficient.
