In order for something to be completely free, it must be without cost. You are using "free" to mean "unpriced," I am using it to mean "without cost."
I'm sorry but what I meant with free is not "unpriced". There is a price. It's zero.
"price" is defined as the number of some market element (typically money) which must be exchanged in order to get the item in return. Perhaps you are equating "unpriced" with "undefined" (the mathematic term), but in the sense we are speaking of, "unpriced" and "0 price" are the same.
In order for something to be "without cost," the production of that good must: a) be infinite and b) not reduce the ability to produce another good. That is what is meant by "scarcity" in the economic sense.
If by cost you mean "what you need to provide to produce something", then yes, there is always a cost. You need time and you need energy for instance. But to me it is not incompatible with the idea of something being "free", as in, again,
you don't have to pay anyone to have it. To me if I can build a boat by myself, using wood I found in a forest, this boat is "free". I did not pay anyone to use this wood and I used my own work. And if one of my robots does it for me it's even clearer since I didn't even work, I just ordered him to do it.
No, the boat is not free. It cost you a house. Or several statues. Or toothpicks. Et Cetera, Et Cetera.
https://en.wikipedia.org/wiki/Opportunity_costIf your robot did it, it also cost you the energy it took to run your robot, and the robot itself cost a considerable amount of energy to make.
Again, you make the mistake of seeing only the price tag, and ignoring the greater truth: that nothing, even if given away without price, is not free. Everything has a cost.
Is it possible for production and transportation to be so cheap and abundant so as to be "unpriced"? Possibly.
It is priced. If you want something that you can not produce yourself (because you don't have any robot, in which case you'll probably ask for a robot), you might find someone (at least one person), that will give it to you without asking any payment (because he will just order one of his robots to make it). By definition, it will mean that the price will be zero since at least one transaction can occur at zero.
price ≠ cost. The recognition that everything has a cost is what creates the price system in the first place.
We'd probably need to be a
Kardashev Type III civilization, though, harnessing vast amounts of energy.
It very much depends on the size of the human population in coming centuries. The power of the sun can totally be enough, as we don't have to spread through the galaxy. Growth is not inevitable.
No, it is not.
But time is limited. In just a few billion years, that sun will destroy this planet, and anything still living on it. So while growth is not inevitable, it's still a good idea.
But no matter how advanced we get, we will never escape scarcity (see above definition). Since that is a physical law of the universe, I don't see money disappearing any time soon, no matter how cheap things get, simply because it makes it easier to wrangle the necessarily finite production and transportation capability of the universe.
Post-scarcity economy does not pretend to violate mass-energy conservation and things like that. The fact that production capacity has to be finite does absolutely not mean that it can not overwhelm human needs and desires.
I think the core problem we're having is you're still using the "shortage" definition of scarcity. You cannot get past the physical limits of scarcity, but you can certainly achieve abundance and therefore extremely low prices.
You guys are arguing in circles.
Is air scarce? There is only a limited amount of it but still there is enough air available for everybody.
Air is not only
abundant, it is everywhere people need it. Except underwater. And in tires. And hey! They charge for filling up scuba tanks and tires, don't they? And using the Economics definition, yes, air
is scarce. The same air which I am currently breathing cannot at the same time be used by you. Should we attempt to do so, we would both die.
