I don’t think this is an actual stable world. It is too easy to destroy everything with one typo. Also, there are lots of things that are in practice world disrupting that are easy to describe. Duplication of arbitrary matter. (including humans) Conjuring of energy. Making an object infinitely strong. Controlling the flow of time. Portals.
I suspect that in such universes that are not destroyed very quickly, an early user creates fail-safe spell constructs that limit such destruction by future users (including themselves under most conditions). This does leave open the possibility that some primordial magic user with root access still exists somewhere, and is very careful to use such power only when absolutely necessary, and only with the minimum weakening of ordinary constraints.
