Well, then that's simply the claim that markets solve all problems optimally ... which is equally bullshit?

> Every specialization is about knowing the level of integration and specialization.

So ... specialization is always better, except when it's not? Yeah, duh!? How exactly does that help us with determining what the right level of integration and specialization is?

On a personal level, the “right level” depends on your disposable income and your talents. I have the disposable income to throw money at a lot of things that I don’t want to do - not bragging almost any software engineer in the US should be at the top quintile of earners for their local market.

On a broader scale that’s the entire idea of the value chain.
