You dont need deeper understanding of knowledge for everything. Ask Grandma whether she needs a chemical engineering degree to bake apple pie.
Then there is the Theory of Bounded Rationality which tells us expertise may exist but resources, time, energy, info, attention etc etc may not therefore bounds and limits of expertise alone must be recognized and solutions reached are satisficable rather than optimal. Aiming for optima when other factors havent been sorted just creates new problems.
