OTOH, despite uniform similarities, no one ever identifies the ships in "The Expanse" as Starfleet vessels in the first place.
Sorry, but that one has always been incredibly weak. We know what sort of uniform the skipper of the
Intrepid wore - not "similar" but same. We know there was succession from that skipper to a UESF one in "Twilight". The rest is just pathetic wriggling.

It was disbanded because Starfleet is not a military organization. That's from dialog.
Let's retrace the missing step, the one where the actual dialogue is considered:
"He was a Major in MACO which took part in a lot of old world combat."
"He was a soldier..."
"Aye, sir. He was pretty good one. His military service came to an end when MACO was disbanded."
"Why? What happened?"
"The Federation, sir, Starfleet. We are not a military agency. Made him a captain and gave him the Franklin."
The disbanding happened. Nobody asks why, and nobody tells why. Instead, the question is posed why Edison's military service came to an end when the MACO was disbanded. Since the fact that the MACO was disbanded does not yet answer the question, we must accept that some other organizations allowing for the continuance of Edison's military service would have been available, resulting in the "huh?". The answer then follows: the Federation cut short Edison's military career by making him a Starfleet Captain.
There's a third interpretation readily available, too, a nuance on the above two. Because Starfleet is not a military agency, they were told to give an ex-MACO a ship to perform the military role with, in some non-Starfleet organization starved of ships and good men. The Federation dictated Edison's career move, and the Federation told Starfleet to donate a ship to the Federation Conquest and Bloodshed Force.
But that one doesn't work very well, because Edison no longer has a military career once aboard the
Franklin. And not just for certain semantic values of "military" - he specifically hates being a de facto civilian, a noncombatant.
If Earth had a military fleet during those wars -- and it very well might have -- then MACO is a possible candidate for who was actually operating that fleet.
So is the American Continent Institute, or the Chinese People's Liberation Army, etc. But none of these compete evenly with UESF, which existed and fought space wars at the time, and never complained about lacking a monopoly.
Endless postulating just doesn't suffice. We never saw a MACO ship, unless it was sneakily camouflaging as something else. We never saw a MACO starship operator, unless he or she was sneakily camouflaging as something else. If there were at least
something to grab onto, some
hint that the MACO had their own ships... But no. When the MACO sail to save mankind in ENT S3, they get on board a Starfleet ship. Do they send a clandestine shadow mission consisting of their own, slower ships? Postulating, postulating.
It's much simpler to postulate that which is all but demonstrated already: that Starfleet does the fighting, while the MACO train in classrooms and simulators for a ground fight that never comes (not against the specified Xindi or Romulans, at any rate).
It's not really an "idea." Edison was given command of a Starfleet vessel, so we know of one case where that actually happened. There's nothing to suggest this is a one-time deal. It also kind of suggests that Edison had deep space experience, commanding a Warp 4 ship and all.
Jonathan Archer was given command of NX-01. It certainly looked like a one-time deal. Silly political stuff happens, and the results in both the above cases are tellingly disastrous.
But the point with Edison's transfer is that his skill set is wasted. He doesn't get to do what he was trained and indoctrinated to do, and is willing to go to genocidal war for the very issue. He may have been doing Starfleet as much good as the late Sen. Glenn did for NASA in politics, but a continuation of a role it ain't.
That's actually likely to be true, this being Star Trek and all. The kind of weird shit Starfleet has to defend Earth from all the time is actually the reason they don't work as a military organization: because military solutions rarely (if ever) work for Earth and tend to backfire spectacularly.
Now we're back on common ground... But the early days of Earth's interstellar fighting forces wouldn't yet involve a long tradition of abandoning the even longer tradition of bravely kicking at the enemy until one or the other wins.
(Or would they? Perhaps the Xindi struck Earth back when there were plenty of conventional armed forces but no space warfare capacity yet, not after the WWIII losses, and some weird brain trust defeated the Xindi with the help of mimes and cucumber farmers, prompting politicians to place armies in permanent disfavor?)
