It's quite a shallow idea that right and wrong in life are exclusively related to consent. Just building on that concept (not to compare to software issues), one could say that it's fine to own slaves as long as they consent to selling themselves to you. Ethics is clearly far more complex than just the issue of consent. And that even ignores the issue that the real world is far removed from the abstract principle of consent given imperfect power balances and imperfect knowledge on each side.
