I would love to live in a society that would recognize the post-scarcity nature of many goods nowadays and de-commodifies them, including computer programs, basic food, and in certain cases housing.
There will be no more "scarcity" when the "value" of the time required to produce these works reaches "zero." Until then, there will be plenty of scarcity.
By the way, I think we would all need "immortality" in order to reach that point.
So, yeah.
Not going to happen.
Bits on a computer that can be reproduced forever are not scarce.
Some people don't seem to value the effort required to create new ideas. Hence, they are seen as "free" and not worth anything.
A car is not just an object, a car is also an idea. It's a design, the engineering of its parts, the implementation of its constructions, the code needed to make it work, and so on. And yet if we could replicate it for free, achieving a marginal labour cost of zero, then it would not be scarce anymore.
You are getting too caught up on the fact that some things have low marginal costs to produce that you're entirely neglecting that overhead costs are a thing that also exist.
Even for something like Linux, there are gigantic overhead costs. The vast majority of Linux commits are made by people sitting at their paid job. Those lines of code are not free, they are financed by the companies who are willing to pay Intel/IBM/RedHat etc for their products and services.
But we don't live in that society.
I guess we could argue about semantics but depriving me of my ability to legitimately profit from my work while the IA wrapped itself in a flag of doing good seems like at the very least a very low form of behaviour, as well as illegal. And I doubt many people would describe us any word other than theft.
It is theft in the same way that someone squatting unused land in the north of Canada and being granted ownership is theft. The fact that we live in a system where this might cause loss of income for someone is neither necessary nor the moral responsibility of the Internet Archive, SciHub or Library Genesis.
