The question "Why does something exist instead of nothing?" is different from "What caused the Universe?". The former question is not asking about causation in time.
Suppose that your interlocutor grants that some event didn't need a cause, so that the Big Bang didn't violate causality. Well, the occurrence of no event also doesn't seem to need a cause. That is, causality would still have not been violated had nothing happened. So, it still seems reasonable to ask why something happened rather than nothing.
Although not a complete and satisfactory solution, my favorite answer is this one.

Yes, that's true; I tried to distinguish them in my reply, because the point about time and causality doesn't really apply to the something vs. nothing question.

This post grew out of a very long discussion with the New York Less Wrong meetup group. The question was, should a group dedicated to rationality be explicitly atheist? Or should it make an effort to be respectful to theists in order to make them feel welcome and spread rationality farther? We argued for a long time. The pro-atheism camp said that, given that religion is so overwhelmingly wrong on the merits, we shouldn't allow it any special pleading -- it's just as wrong as any other wrong belief, and we'd lose our value as a rationalist group if we began to put status above truth. The anti-atheism group said that, while that may be true, it's going to doom us to be a group exclusively for eccentric nerds, and we need to develop broad appeal, even if that's hard and requires us to leave our comfort zone.
Things got abstract very fast; my take was that we need to get back to practicalities. Different attitudes to religion have different effects on different types of people; we need to optimize for desired effects and accept what tradeoffs we must. We can't appeal equally to everyone. So I came up with a sort of typology.
