This is exactly the kind of discussion where the difference is important. Your reading of the point they were trying to make is impressively charitable. I shall try to learn from it.
If the point is that anyone can tell anyone else anything, that's vacuously true but a court typically wields the power of a state and its code of laws. For treaty countries ICC is perfectly unproblematic but for nontreaty countries there's a strong difficulty in calling it a court as it bears no legal legitimacy.
