Full Idea
Having a particular average kinetic energy is only a necessary condition for having a given temperature, not a sufficient one, because only gases at equilibrium have a well-defined temperature.
Gist of Idea
For temperature to be mean kinetic energy, a state of equilibrium is also required

If you try to pin it all down more precisely, the definition turns out to be circular.
