The way I read it, the post primarily advocates a focus on being sustainable and profitable rather than optimizing for a VC raise. You said as much yourself in the recent TC article on Referly's seed round, no?
As the common wisdom goes, the best way to raise money is to not need it. Whether you decide to take funding at that point to accelerate your growth is up to you.
While looking to raise capital and "go big or go home" is perhaps a good barometer of desired impact, I don't think it necessarily correlates to actual impact. From personal experience, there are plenty of companies that go through accelerators or do the "startup" route that are completely optimized for a flashy launch and raising a few $MM. Even if they do eventually prove to be disruptive and earn an exit, the definition of "impact" is a separate discussion, and, I would argue, not solely based on sale price or how many users you've obtained.
