I'd love to see a change where the federal government was no longer allowed to tax individual citizens (or companies?). Taxation should be done by their State of residence/employment, and the Federal government can tax the State. I'm not sure what else could be abstracted this way so that the citizen wouldn't interact so directly with the federal government. Things like the DoE, and HUD, could probably be eliminated while things like the FDA and EPA really should have federal reach to execute their missions properly (not that they're really doing that).
