Len, I'm not an anarchist, either . . . but IMHO a good portion of the Federal government - as well as state and local governments - actually could be eliminated.
Some years back, when I lived in MN, there was a strike of state employees. Except for some students at U of MN who had to stand in line longer, virtually nobody noticed. Lights stayed on, water flowed from taps, sewers worked, schools stayed open, police, fire, and EMS continued, doctors kept doctoring, private businesses continued as usual . . . once people started asking "Who NEEDS these strikers, anyway?" the strike was settled.
I think the same would apply to a lot of the Federal government.
