Maybe that's a good solution for the particular problem you mentioned, but the only way to banish "moral crusades" which seems in this thread of discussion to be an allusion to the political aspects of economic activity is to price everything correctly everywhere and reduce transaction costs to 0. Not convinced it would work, and if it could work, the only way we could approximate such a solution is by incrementally restructuring the economy as new solutions are developed in order to test them and keep the ones that work. This is a fundamentally political process. There's always an undertone of banishing the political from human activity leaving only economics in conversations like this one that doesn't sit right with me.
