Its helpful but not always important
What you are saying is like saying "a red light isn't important in and of itself, it's more about whether you actually stop at the intersection." True only if one assumes that one will act properly regardless of the sign. But that is simply not the case. Why would you stop if don't see the light? You'd assume there is no danger and keep on going, in all likelihood.
Not exactly, although I see where your coming from
You can see the sign, and know it means danger and stop
You can see the sign, ignore it and be harmed
You can see the sign, misinterpret it and be harmed
You can not see the sign at all
However some people can not see the sign, and still skip danger
OR some people can ignore the sign, and skip danger
