Does he, though? Maybe to him the experiment is the research. It's ok for you and him to have different approaches to learning. As long as he's comfortable with losing his investment, let him learn from his mistakes.
My concern is that Amazon will shoot first and ask later. If you get suspended for violating the rules on Amazon and your plan of action is denied, then that's it. There's no second chances. No "stealth" account that will get you back to selling long term.
That is why it's so important to research first, and act second. There is no undo.
