It's irrelevant if the set of possible insults has infinite cardinality since we only care about the actual insults litigated on. If there is an insult which isn't in the list, the courts could decide if it fits their definition and through precedent it would be implicitly added to the list.

It's very relevant if you want a 'perfect' definition/insult list, but noone in policy land aims for perfection because they live in the real world.
