The spov levels are neither "arbitrary" nor without "real reason"?
What you are asking for is something that distinguishes the human social 3rd level
from other animals' 2nd level.
IMHO this distinction lies in the self-conscious rule-following and institutions of humans.
However, note that there is nothing in principle that prevents other animals from
obtaining the 3rd level.  It just hadn't happened in Pirsig's time.
And conversely there is the human social 2nd level.
