It seems that the only barrier between brain state and thought contents is a proper measurement tool and decoder, no?
We can already do this at an extremely basic level, mapping brain states to thoughts. The paraplegic patient using their thoughts to move the mouse cursor or the neuroscientist mapping stress to brain patterns.
If I am understanding your position correctly, it seems that the differentiation between thoughts and brain states is a practical problem not a fundamental one. Ironically, LLMs have a very similar problem with it being very difficult to correlate model states with model outputs. [1]
