You have misunderstood what I am saying. It is definitely not a consequence of my claim that there are no erroneous or unfounded beliefs. One can have a mistaken belief about Obama (such as the belief that he was born in Kenya), but for it to be a belief about Obama, there must be some sort of causal chain linking the belief state to Obama.
So what you mean is that the Boltzmann brain can have no causally-connected beliefs about Obama, not no beliefs-as-everyone-else-uses-the-word about Obama. Fine, but your original statement and your clarification still gratuitously repurpose a word with a conventional meaning in a manner that will be actively misleading to the reader, and doing this is very bad practice.
