I'd argue that's precisely the point of electoral politics, checks and balances and the federal rulemaking process: a bad-decision making agency to Elon (say, FAA oversight of SpaceX) is a good-decision making bureau to others. None of the three are involved at this point, and by the time these cuts are litigated in the court of public opinion (and not, say, Twitter), it'll likely be too late to reverse them if desired.
