Mbh 12.68.4b

If the king did not protect, everything would be exterminated prematurely, and every part of the country would be overrun by robbers, and everybody would fall into terrible hell. If the king did not protect, all restrictions about marriage and intercourse (due to consanguinity and other kinds of relationship) would cease; all affairs relating to agricultures and trade would fall into confusion, morality would sink and be lost; and the three Vedas would disappear. Sacrifices, duly completed with presents according to the ordinance, would no longer be performed; no marriage would take place; society itself would cease to exist, if the king did not exercise the duty of protection. The very bulls would not cover cows and milk-jars would not be churned, and men living by rearing kine would meet with destruction, if the king did not exercise the duty of protection. In the absence of royal protection, all things, inspired with fear and anxiety and becoming senseless and uttering cries of woe, would meet with destruction in no time. No sacrifices extending for a year and completed with presents according to the ordinances would occur if the king did not exercise the duty of protection. In the absence of royal protection Brahmanas would never study the four Vedas or undergo austerities or be cleansed by knowledge and rigid vows. In the absence of royal protection, the slayer of a person guilty of the slaughter of a Brahmana would not obtain any reward; on the other hand the person guilty of Brahmanicide would enjoy perfect immunity. In the absence of royal protection, men would snatch other people's wealth from their very hands, and all wholesome barriers would be swept away, and everybody, inspired with fear, would seek safety in flight. In the absence of royal protection, all kinds of injustice would set in; an intermixture of castes would take place; and famine would ravage the kingdom.
