End of story.
Not at all. You're oversimplifying. If offset were truly DC, it wouldn't
drift. And it does drift. Likewise, white noise also has an (infinitesimal)
component at DC. It isn't all as black and white as you claim it to be. I
realize this is a very theoretical approach, but I stand by my claim that
offset and noise are conceptually similar.
