The woman is irrational to conclude she should have the extra male at the detriment to society.
Why? It's precisely
your norms of society that postulate this. How can you assert that your metrics are universal?
Besides, it's cherry picking, since conflicting norms can be discovered for other reasons of abortion. What makes this stand out?
Two people can abide by the Golden Rule and reach entirely different conclusions.
Precisely. But I don't think the gist of Hawker's point depends on the golden rule, but on consistency in ethical reasoning.
For example, we want Bitcoin miners to defect against one another, not conspire to keep profits high!
I partially agree, but I think some issues are conflated here. We want them to defect against one another, because the system is built upon a descriptive reality that they would do so. If they don't, the system wouldn't work efficiently. So it's specific to the technical context. In a grander context, we would prefer the miners to keep mining even if it's unprofitable, since it would help the network. This won't work of course, but it's still desirable.
I'd like to defend
dayfall here, because I agree that acting towards an enlightened self-intrest
is rational, mostly because of transcendental issues. Not overreaching towards something above your life does not make much sense, and you are not doing it anyway. Even if you are a reptilian bastard, what you call immediate self-interest would still serve something greater than your life, be it continuation of your genes, or your attitude itself. So, while you're at it, why not work towards creating a more coherent perspective? The reason I don't agree with
dayfall is, that this resulting perspective does not need to conform with his/her particular world view.
