All societies exist on a "law" to "rule" spectrum, what determines whether you have law or rule is who the final arbiters of justice are.
If citizens themselves are the final arbiters of justice, you ironically live in a law based society. If those with power are the final arbiters of justice, then you live in a society with rules, not laws.
The absence of law is rule by those who are most powerful. The explicit purpose of law is to prevent arbitrary wielding of power.
With this understanding he's correct, because law is an entirely self fulfilling prophecy. If GP does not wish to enforce the rule of law himself, then there is no law.
The preamble of the declaration of independence states this idea more eloquently. The person you are responding to doesn't feel any personal responsibility for protecting a law based government, and if everyone feels that way, whoever has the most power gets their way, because who is going to stop them, who will provide consequences when the legal system is a weapon of the powerful, rather than a check on power?
