The aspiration is not a zero sum game though; as I understand it there are negative aspects to it to, not least that it is painful.

Before anybody asks me to defend that, let me say just please don't ask me. People with actual knowledge and expertise in this, all over the world, have decided its not worth it. Some countries have decided otherwise, and that's their prerogative, but most have decided not to. So let's just get on with it. Things should be questioned, for sure, but frankly, not by unaffiliated people who have a popular YouTube channel.
