> Video game addiction (overuse) is a coping mechanism in the face of increased anxiety in the modern world.

You are stating this in absolute terms, which indicates to me that you have a solid source, or are an expert in the field. If so, can you please detail?

From my background working in psychiatry (in-patient) for six years, it is certainly not that clear.

> Real addictions have severe physical consequences like chemical withdrawals that can lead to death.

So the sex addicts I treated didn't have a "real" addiction?

The gambling addicts I treated didn't either?

Or the extreme adrenaline addicts?

Also, many experts in the field seem to disagree with you. See the proposed internet gaming disorder [1].
