I understand the distinction, but I would say that given the overwhelming documented causal relationships demonstrated already, it is rather the quantum physics people to come up with a model to adequately explain "uncaused events" rather than expect the whole Newtonian world to bow simply because they have not been able to draw the same relationships between activities we see in the "big" world.
You assume the quantum world is deficient in some way, but physics assumes that the rest of the world, including relativity, will be assimilated into QM.
