Insisting on Pareto optimality with respect to your values does not rule out all unreasonable policies, but it does rule out a large class of unreasonable policies, without ruling out any reasonable policies. It is true that the theorem doesn’t tell you what your coefficients should be, but figuring out that you need to have coefficients is a worthwhile step on its own.
