Unless you just mean we could do exactly the same things, but more efficiently. But that is not what is meant; it means stopping doing a lot of things.
Very efficient
The real story is that he's anti-anti-competition. His competitors in particular already have deep ties with the government and its various departments. Companies like Boeing, Lockheed, etc. have engaged in deep regulatory capture to prevent competition from emerging.
These already established corporations have a revolving door with the government and that's the real impediment. That's what he's against.
So while you're right about his self interests, I think it's important to clarify that the decades long entrenchment of these various incumbent corporations is why this is all happening in the first place.
That's the real reason.
which <could> influence
That's a silly way to weigh your decisions and valuations. "There are more than four hundred federal employees, that's more than the number of states."
The number of agencies is itself mostly irrelevant, it's their individual size, effectiveness, and appropriateness that matters. Do all of them need to exist? Almost certainly not. But do we need to cut it down to one per US state? That's an arbitrary and useless target.
I'm sure they could be reduced down to similar areas of operation. One of the first to be cut being The California High-Speed Rail Authority (CHSRA). Who has so-far spent 16 years building 119 miles of track at a cost of $14 billion. That's roughly $66,845 per yard.
Using the number of states as some yardstick makes zero sense: merging multiple current states into one wouldn’t make our society less complex.
How can you POSSIBLY state he is "strongly antigovernment"
uh, what do you base this on? it sort of seems like made up bullshit, especially because it's easily disproven by tracking his jet and seeing that it's visiting the locations of his offices in both california and austin frequently. there's even a video of him in one of his offices literally yesterday as he did a zoom meeting for WSJ.
i don't understand why people just blatantly lie like this
