why is there an option to ban no champ in champ selecT?

i find a really bad feature since in low elo most players equal not banning a meta champion or a hard counter to him or a teammate as skill not just not using your brain and literally increasing the chances of loosing again. now i dont mind about him but if im part of his team why should i pay for it when he looses the lane hard bc the counter actually get picked only bc he does not take his free ban option?
