You're pulling the same skit you pulled before, with the half and half argument.
Take half, and leave half out.
The post is a little broader than that. It's not pulling a hypothetical, where you assume you HAVE to be a celebrity, it asks how famous do you have to be? Not how famous do you have to be - assuming you have to be a celebrity of some degree. There is no base minimum, therefore ZERO can be an answer. Oh, btw it is.
And besides, here's my "so"
Out of 20 dicitonaries I just checked, guess how many of them have your definition above mine? One. That's right, and no I didn't pull the the one you pulled it from (that would just be cheap, so if you want instead counting the below as 19 to 1, you can count it as 19-2 if you throw yours in).
19 to 1. Still going to argue the favor of the majority, despite that most masters of the art of English disagree with your definition?
The popular opinion here seems to be in the favor that you do not have to be famous at all.
Actually yeah, let's continue using the popular opinion.
