Sure, but I reject Wittgenstein's puritanical positivism. Language can cause some confusions, but that's not the source of all philosophical problems.

"Meaning" has multiple meanings. We're not talking about semantic meaning but purpose. And your second point about the futility of discovering meaning as a concrete object presupposes atheism. If God exists and has a plan for us, that plan could indeed be discovered (in traces of the supernatural domain).

Wittgenstein was like Hume in thinking that lots of philosophy and theology can be dismissed as meaningless, but their criteria for meaningfulness proved to be arbitrary and self-refuting.
