I think you'll find many people actually do understand it. In fact, you generally shouldn't predicate your argument on the idea that "literally nobody understands" a thing, because that implies you're directly aware of the entire scope of literature around the subject and its implications.

Aside from that, inability to understand a thing should really count against it. Or do you suppose Miyazaki's Inter-Universal Teichmüller theory is strong because it's borderline incomprehensible?

Like I said, Occam's Razor suggests there really isn't much there.

Funny, some suggest Occam's Razor is just a paraphrase of Gödel's theorem.
