In one sentence:
You should consider going to VCs when you already have a business that works, when money is the limiting factor to growth, and when there is a land-grab-like advantage to growing faster than your competitors.
It has nothing to do with the kind of lifestyle you want, or feeling overworked, or personal autonomy, or mastery, or wanting to create a fun work environment. All of that gets more stressful after you raise money, not less.
It sounds like the author was feeling frustrated after having tried a bunch of things that didn't end up being profitable. That's totally understandable, but it's a terrible reason to raise money. You don't raise money and then figure out the business later -- you figure out the business first, demonstrate that it works, and convince people that it would work better/faster with access to more capital.
