You miss an important aspect. You won't succeed in 100% cases you don't take
an action, but you also don't fail due to your lack of skills in 100% cases
you don't take an action. You can't be blamed for failing if you didn't even
try. You can only be blamed for not succeeding.
No, that's not how it works, which is the point. As they said, men's value is judged on their current success. Not trying makes you just as valueless as trying and failing, it is the exact same outcome.
