9 Peano axioms, 3 types of radioactive decay, 8 planets (are dwarf planets "arbitrary"?)...

Yes, you lost me at planets. I don't know which group of people it was that collected enough status to declare that Pluto is not a planet (or more precisely to alter the rules by which planets are defined) but the list is arbitrary on approximately the same level as the categories of moral values---based on something that does exists in the world but sliced into fuzzy categories based on convention or authority.

Stipulating agreement: aren't fuzzy categories better than no categories at all? Who was the first ape classifiable as homo erectus, and how distinguishable was he from his homo habilis parents?

Oh, I agree with your conclusion---arbitrary categories are great. I'd go as far as to say indefensible (for us, at least).
