The unelected bureaucrats should be responsible for upholding the Law and the mandates of their position, not to any individual or party. And the Law is set by Congress, not the Executive. The Law is enforced by the Judiciary, not the Executive. The whole point is to have an engine that can keep working and keep accumulating domain expertise regardless of which political party is in control, beholden to the Laws set by the Congress over time, representing all constituents over time, held responsible by the courts, and not the whims of any given administration (or, for that matter, any single Congress). The entire problem _is that_ we now have what may effectively be lifetime leaders being put into positions and _being told to ignore the law and their government issued mandates_.

And so much reeks of a Watergate like situation, except done publicly instead of in secret, with Congress and the Judiciary refusing or unable to hold any of these people to account. "We will now gather all information about our adversaries and fire anyone who doesn't give us the keys to the vaults, and if anybody doesn't like it, good luck, because the courts are going to be VERY busy, indefinitely, as we proceed to break every law the Legislature has issued, and is unlikely to have time to hear your case for a few decades."

But let's take at face value the idea that the Executive doesn't need to follow or even acknowledge the decisions of the Legislature, and that they can tell anyone to do anything whenever they feel like it. There's a pragmatic issue, not just a separation of powers issue: How can you possibly accumulate domain expertise, and what motivation would you have to accumulate that expertise anyway, when every agency is going to be dismantled every 2-4 years?

Besides, these bureaucrats are "elected" in a way similar to the Electoral College. We vote in the Legislature, and the Legislature votes on the appointments. If we don't want "lifers" then we should be voting on term-limits for these positions, not allowing the wholesale remodeling of our bureaucracy every election, where "just anybody" can come in and walk away with whatever they can loot each cycle.
