Maybe they would be better categorized into some group that is more appropriate, but then you lose the possibility of someone within that knowledge domain being able to answer the question appropriately.
Those questions run right alongside reading documentation for fun.
I suppose an overhaul to the infrastructure of question answering could help solve this problem - like questions have a maturity cycle / process in which they are developed into a more refined / edited sorts of comprehensive documentation, or even a better 'smarter' way of linking clusters of question together, or a way of moderating the authoritative direction of a question (rather than delete or replace, show a progression of modifications so people can learn what are model questions and what are less useful kinds).
Getting people to stop asking kinds of questions will never work, because they ask those questions precisely because they have not been trained in any sorts of formal internet etiquette. If you want to prevent the community from collapsing in on itself, I think the best solution is to modify the flow and connectivity of questions, so that they are intelligently inter-related, rather than relying on a sort of competitive singular universal form.
