So, what's the "content" in your example? I don't see that the example sentence has any content and so I don't see how it's relevant. If one were to say, "It is false." the natural response would be, "Huh?" or "What's the 'it'." There's nothing there that can be false. it's the same with the sentence, "This sentence is false." (Or, for that matter, "This sentence is true.") In order for something to be true or false, there need be something referred to.
I understand the stakes here and the ultimate conclusions that Godel came to with a related inquiry, but I can't get past the fact that there needs to be some content for the sentence to be admitted to the true or false game.
The part that says "you should give me all your money". This is a clearly meaningful, contentful sentence. (Unfortunately for me, a false one.) Embedded in the reflexive sentence, it gives a reflexive sentence containing content. However, such sentences render the system inconsistent, so excluding empty circularities like "this sentence is false" is insufficient to resolve the problem of deciding what circularities can be admitted.
