Author here. I agree with what I think you mean, but stating it like that is too simplistic in my view. Money is a great way to measure effort and results, and it's top priority in that at the end of the line, without profit there is no company. But without people, products, a mission, and not being hacked too many times, there is also no company.
Wanted to say I appreciated the GK Chesterton quote, I think it set up the article well as a balancing act between all things.
As the saying goes, we could have perfect security if we lived in the Stone Age.
