You can choose to give your consent to activities like exploiting code though. You can consent to being in a fight (e.g. boxing or mutual combat states). You can consent do whatever with your code (e.g. CTF style sites). To me, it seems like saying "Code is law" or allowing people to create arbitrary proposals and voting on them with loaned money is kind of consenting to whatever happens.
There are things you can't legally consent to. You may able to consent to being in a fight, but you generally can't consent to a fight to the death (e.g., a duel). Nor can you generally enter into an agreement to commit fraud, or other illegal activities.
