> who will enforce the redundancy?

Who enforced the redundancy of humans possessing two kidneys? If you are a creationist, then I guess we have different starting assumptions.

Assuming that you aren't, then you would understand that redundancy in humans literally evolved from randomness and volatility. Evolution is a hill climbing algorithm - the organisms that survive the best reproduce more and become more prevalent. For me, nature is perfectly laissez-faire, there are no circuit breakers in nature, there is no enforced stability.
