you trying to hold me personally responsible for other people accountability is at a foundamental level a repeat of the same deflection tactic as expressed above, and warrants a repeat of the same general concept: I do not bear any responsability in the atrocities that far away government allow to be inflicted on their own populace, and I do not profit from them, and the accountability rest on the government of the oppressed population, and they are accountable to the oppressed population and no other.
On the other hand, extrapolate your own question to the only logical conclusion, see how it goes. You cannot boicot sweat cobalt, there are not enough "sustainable" mines for that. Option two is either santion these countries into the ground or to invade then and export democracy. Good luck with that, bet their population will be real glad of your help. Your line of thinking is circular, offers no actionable solution, and it's ultimately just a way to distribute guilt moving it from the people actually exploiting the situation to people that have no choice in the matter.
