If necessity was a generator, a vector or force for movements or actions, then I could understand that use of "out of". Out of indicates the result produced by a force, algorithm or oracle. But I consider necessity not as a generator or force but as a passive state. Hence I wonder what is the mechanism for this use. If we collapse the concepts of passive and active then I think language get corrupted and poissoned. Analogies are not fruitful because they go far beyong the logical ground. I believe that if you are going to get something out of a state then that state should be a generator. I don't know if what I am trying to say is sound but I sharply feel the unsoundness of linguistic non logically generated derivations
