If you don't even know what that would mean then it's premature to declare that nothing works that way. Understanding the meaning is a prerequisite for that.
In this case, it may help to understand that e.g. border control enforces a traveler's permission to cross the border, then lets them proceed.
> some people would expect it to enforce that the pointer is non-null, then proceed
No language magically makes the pointer non-null and then continues. I don't even know what that would mean.
