The main problem is that why just doesn't exist. There is no why. I can choose an arbitrary answer to a why question every single time. We are mostly satisfied with a how answer to a why question. And most why questions are in fact how questions or just used for something else (like defiance from a kid asking why they have to go to bed). Also we stop asking why when we are subjectively satisfied with the answer, not when we've found "the cause". And we've been conditioned since we were kids to feel it's rude to ask why more than once or twice.
