Wrong. Written like someone with no understanding of the law. All of those things are authorized by, or interpretations of, laws. A court decides what the law means. That is its proper role. Its decisions determine the effect those laws have. An executive order is the president exercising his pre-existing authority, granted in either law or the Constitution. He has no ability to make executive orders that are otherwise. Agency regulations are made by explicit grants of authority in the law passed by Congress.
All of these things have the root of their authority in laws.

The legitimate responsibility and authority resides with the body that created the law.
