He is well aware that on many 2 and 4 place aircraft you can't fill the
seats with adults and fill the tanks without the W&B being out, so he

This is a standard mxmanic deflection tactic.

The only deflection is yours. You still have not answered my question: Name
an aircraft that will be overweight with a full load of fuel even with only
the required pilot(s) on board.

The fact is, there is no such aircraft, and you know that, which is why you
won't answer the question, and it is also why you try to divert attention from
the fact that you have not answered the question.
