This reads like an idealized version of reality. Budgets exists, deadlines are a thing. "Don't be a hero" sounds like the mantra of an HR department at an insurance company; not what you want to hear from a founder trying to disrupt an industry.

Heroics can exist without them being a standardized thing. There are occasions when you need people who are willing to move mountains to get something done, and demonizing those kinds of efforts and the people who engage in them will make them scarce when you actually are in need.
