That's kind of the point: they're doing no such thing.
All of the talk from Trump, Musk, the now-departed Ramaswamy, etc. hasn't been about sober analysis and careful evaluation, it's endless mockery and dumb jokes ("look at this agency name or person's title, what does that even mean LOL"), or "government bad" as the parent put it.
The pushback this gets isn't because people love bureaucracy or hate efficiency but because it's obvious this isn't an actual effort to improve anything, just mindlessly slashing things businesses/the powerful don't like and stunts to make the base clap.
