This is a helpful summary of our differences. The keystone is whether zero-sum is a good framing or not.
I think we should by default assume we're in a zero-sum regime anytime people's attention is involved. For example, think back to the SOPA/PIPA boycotts a few years ago when every website turned off for a day. That's a trick you can only pull a finite number of times before people grow jaded.
Similarly, someone is only going to try to learn programming a small number of times. And every time they think they failed increases the energy barrier for the next time. Burnout is the primary concern here, to my mind.
The same principles apply also to experienced programmers learning about new software. Burnout is the prime enemy, but the concern of minimizing burnout is on no author's mind. Nobody owns the design goal of comprehensibility of internals. Lack of ownership is the essence of an externality.
When it takes too much effort to comprehend a piece of software, people can no longer keep up with it on their time. They have to be paid to do so. That biases the playing field between insiders and users. A small number of people working on a popular piece of software can have disproportionate influence on the lives of people.
To me the argument of the previous paragraphs is ironclad. Which part do you disagree with? Is software already easy to comprehend? Is comprehension to outsiders not the #1 problem in software? Is the difficulty in comprehension not because of tragedy-of-the-commons effects?
I'm going to stop debating the non-software side of things, since I'm not an expert there and I don't really have any solutions to offer. I strongly feel the problems of limited attention carry over there. But it's probably easier for me to convince you of that in the realm of software. Oh wait, one final note:
> Clearly our legislators have no difficulty pumping out more and more laws every year...
Have you not met programmers talented at churning out crap? The difficulty is not in writing new laws, but in having the whole make sense. At least in software the computer enforces some basic checking. If the program crashes, that's visible to all. Contradictions in laws can fester for long periods until someone works up the resources to take a case all the way to the Supreme Court. (Why in the world don't US courts deal with counterfactuals? The whole principle of "case or controversy" (https://en.wikipedia.org/wiki/Advisory_opinion#United_States) is bound up in pre-software thinking. In my ideal world courts would be able to give feedback on bills even before they are turned into Law, and actually influence how legislators voted on them. "Have you considered this corner case?")
