I agree with your list of agencies to eliminate completely. Add to it Department of Energy.
If we handed BLM land off to the states, we could shrink Interior down to nothing. Hand the parks over to the states, you could eliminate it.
Beyond State, Defense, and Justice, the rest are either optional or quite expendable.
As can the Equal Employment Opportunity Commission.
And the Woodrow Wilson International Center for Scholars...
Literally hundreds that can go.
Then eliminate half the federal courts.
And the states that have huge tracts of federally owned land will change from poor to prosperous.
