I think you're giving too much weight to the questioner's feelings, and none to the answerer's. Sure, the questioner might feel unwelcome when answers are curt and elitist. But also, the answerers might feel unwelcome when the questioners don't put in at least some effort in their question. Why do you privilege the questioners over the answerers? As a worst case scenario, how do you plan to supply unpaid volunteers who are willing to spend x10 the effort for each questioner? Many of the policies under fire here came out from people criticizing SO for having too many "spam" questions and not retaining experts' interest.
