Sure, there was always "something" but the something that always was is commonly conceived of as "nothing" by laypersons.

No it isn't lol. Everyone knows that anything at all isn't nothing. Krauss just came up with a misleading title to help him sell a book.

He should have called it "A Universe from Almost Nothing".

Even as a child I knew that something wasn't ever nothing lol.

It's not clear that virtual particles which exist on the edge of Heisenberg's Uncertainty Principle are indeed something as most ontologies consider the concept of substance. They seem to be neither substance nor nothing, making your lumping them into one or the other category more a rhetorical flourish than anything.
