Unfortunately no matter how many times you say this or how much you wish it were true, US (at least) courts have disagreed with you by enforcing contracts of adhesion.
I think we're in agreement, we're just saying things slightly differently. I believe human rights exist and are an ethical imperative whether or not lawmakers/courts choose to protect human rights.
