Yes, it does. Humans lie and cheat and steal and misrepresent. Contractors use inappropriate materials or cut corners. Regulators demand unreasonable operational constraints because of political pressure. Insurers demand unaffordable costs. Protestors fight construction because of unfounded fears. Political stasis prevents sensible waste management strategies. And so on.
