Your premise deals with entropy, which of course, in a thermodynamic sense, deals with the level of interactions between molecules, from which, energy is derived and at the end tends to nothingness as you use up the amount of matter, which is converted to energy, in a closed unit. Your very 'temporary being' will eventually be permanent as it changes to nothing.
The very idea of nothingness is permanent in its grasp, once matter and energy is used up, there is nothing upon which to change this state and thus, nothingness prevails in permanence for eternity.
Also, I don't believe you fail to see that if TAZ becomes non-autonomous, it invariably loses the title of being autonomous altogether and becomes 'TNAZ'. I never said Zoners will stop existing, merely TAZ will change and thus not exist in its current form.
Merely having a child fed doesn't preclude evil. You cannot classify the idea of 'good', in any meaningful sense, without having the comparative of evilness upon which to compare it.
