In that case it's hard to say which deaths are "caused by government". If a government could have imposed a policy that prevented them, are they caused by government? Should we balance that against side effects of such a policy? What about side effects of a feasible way of arriving at such a policy?
If we want to discount such deaths as caused by the government, we will end up with lots of cases of "would not happen but for policy X, but policy Y would have prevented them". From some POV _every single death_ is somehow caused by some policy that's government-imposed. To have a reasonable way to define "caused by government" we need to have something to compare with.
