As much as i disagree with you point of view reducing a pretty good article into a word, i'd rather say i's in fact...

Kind of nihilist.

Or at least a little bit.

But i don't think nihilism itself looks deep into the "be content" part, but way more in the "nothing matters" which is not the point of the article.

Existencialism and Absurdism in the other hand, seems like a "better label" for it imho.
