Trump is acting in the manner of all previous authoritarians: What is good for him is what's good for the country and the laws that align with this are proper, and those that do not will be ignored or changed where possible.

But in totality, the rule of, law and not by law is the foundation of our society, because its benefits are immense and usually taken for granted.
