I’m not from the US so all of this is baffling. In Europe and even South America there’s tons of mechanisms to stop that from happening, and this kind of meddling would seriously result in arrests. However this is happening in the US with these people going completely unchecked. How is that even possible?!
Commonwealth countries have a cabinet system of govt.
Minsters are selected by the cabinet from members of parliament. Departments are closed, opened and altered all the time when there is a ministerial reshuffle ordered by the cabinet.
Any minister could run this sort of operation in their department without palrliamentary approval, and the cabinet could do so for the whole govt (and frequently do).
The US has a presidential form of govt. The presidental office is separate from the parliament. Minsters are appointed by the president and must not be members of parliament.
But the president can’t just choose anyone - they must be members of their political party and they must be elected through a series of member elections and state executive decisions.
The issue here is not that DOGE cannot operate under a minister, its that the president cannot order a political outsider to undertake the duties of a minister properly elected through party processes.
BTW, no such limitaion exists in France - the French president can appoint anyone as minister, they don’t even need to be a French citizen or a residnet in France ! Macron attempted to do this recently but had to back down when the parliament blocked money bills.
