Knocking out USAID, Health Care programs, or the IRS by executive order isn’t how our system works. The Constitution places agency creation and dissolution squarely in Congress’s hands under Article I, not the President’s. Even under a strong unitary executive theory, the President can’t just repeal statutes establishing these agencies; that power belongs to the legislature [1]. Congress also controls the purse (Appropriations Clause), so the White House can’t simply “defund” an agency on its own [2]. Furthermore, the Administrative Procedure Act demands reasoned legal processes; you can’t arbitrarily shut an agency that Congress told you to run [3]. If the President could unilaterally dissolve such agencies, he’d effectively be acting as a dictator, collapsing the separation of powers Madison emphasized in Federalist No. 47 [4].
