I was actually thinking about this as if a tree fell on your house, at least thats what started me. I think I would rather be under the 2x12 than a double 2x4.

A double 2x4 braced every 16" would be stronger.

Moment of inertia for 2-2x4s is 1/4th the MOI for 2-2x12's.
The clear span for the 2-2x4's is 1.33' which is 1/9th the length of the 2x12's.
As you can see, just looking at proportions of eachother it's obvious the 2x4s are stronger.

If so why does code everywhere allow headers?

Well, I assume you like doors and windows, there has to be some compromise, no?
I'm not saying the 2x12's are deficient...
