Proof and necessity are logical constructs. In the messy real world we deal with judgement and experience. The burden is on those who want contrary judgements to be given weight to point to experience and rationales that justify its acceptence, e.g. to reason from sound statistical evidence.
It's not enough to say, "Hume proved we can't really know anything about the world of things." The claim is not that the current system is perfect. My claim is that the system is better than the alternative for certain vocations and that engineering is one if them.
