It is not going to become an actual part of the federal government, as a new agency, unless Congress makes it an agency. And if they do, then Musk likely would not make the transition to head it as that would involve too many conflicts of interest for him (at least if we still consider laws as things that matter in this country, that is definitely a concept that's quickly being discarded by both the elected leadership and the electorate so you may be right).
