You are mistaken.
The federal Constitution sets forth a system of enumerated federal powers and a Bill of Rights detailing specific rights held by individuals against the federal government.
There is no provision of the federal Constitution or federal case law indicating that "encouraging the right thing" suffices as an independent basis for federal authority.
If you believe otherwise, I invite you to reproduce that portion of the Constitution or federal case law.
