It's incredibly elitist to gatekeep people having their plans, actions, opinions, and philosophical ideas taken seriously just because they haven't trudged through the onerous process of considering what humanity has already learned about those things. Do these people expect everybody that wants to profit must try to predict the damage that their actions could cause among people that will obviously be affected? Some people just don't like ethics that much, and expecting them to be beholden to their boundaries is pretty old fashioned.
