But too much system can also cause negative outcomes, because all that system has a cost, both in money and in time. If you add a protection to prevent every negative outcome, your system will never produce anything at all, which is a negative outcome. Every check has a cost. For some checks, the cost is more than it prevents. Don't add those checks, even after the negative outcome happens.
