One has to wonder: how was independent New Vegas even Libertarian BS that relies on gangsters and cannibals?? Whole point of that arc was rebelling against two major powers for whatever reason there was from the players perspective. And the NCR can't really be objectively good unless you compared them to the atrocities of the Legion. Without Caesar and the Legion, one could see NCR at best being rife with incompetent leadership in the form of Kimball wanting his biggest general to take over Hoover Dam and New Vegas to a massacre such as Bitter Springs, which in turn was also a result of incompetence from the military intelligence of the NCR. And I doubt any of the casinos will actually back the player beyond just being one of the major power houses in the Strip itself that would be worse like everything else if it wasn't for an army of robots with a unicycle wheel and a tv screen to uphold the peace.
What does become groanworthy over this is the "whatabouist" claim. Whole point of it was to pretty much just show you how bad the Legion is when you visit Caesar and showing you how much NCR struggles to be an effective force against tribals in pre-war sports gear and makeshift machetes despite the fact the NCR managed to overrun the BOS at Helios, which granted was just throwing more soldiers until the brotherhood had to retreat. Part of Caesar's reason for having a Legion was pretty much him seeing how NCR wasn't much of a democracy when it's first president was re-elected well into old age that she was more of a queen than a president in his eyes.
Honestly, if one really tried to project beliefs and values, they may as well not bother trying to play other paths in the game. Why bother going for a Legion run if one really does have to get so buggered by the Legion, especially if they don't bother playing Caesar like a fiddle.
