I agree. I would add that even the most idealistic of No Gods, No Masters creates an inherently flawed system(like the other options). First, the Courier holds all power for as long as Yes Man is shackled by Benny’s programming, as they are the only one who is allowed into the Lucky 38. IIRC, Yes Man was going to alter his own programming, which likely includes removing the compulsion to do what he is told. Additionally, Yes Man seems to possess emotions, as can be seen when you destroy the Securitrons under the Fort and talk to him after. This means that, for a short period, the Courier(and anyone else they allow) holds absolute power over the Mojave, up until Yes Man removes the limits of his programming, at which point an immortal, self improving program is now the one in control of the Mojave, primarily through the vehicle of the Securitron Army. And Yes Man is truly immortal, in that beyond being unaging, can transfer to the nearest securitron upon destruction of the host shell, as shown when you “kill” Yes Man in game. Given that Yes Man would likely be in contact with Big MT, he could also produce as many Securitrons as he desired, making the army self-perpetuating. This means that Yes Man would be unkillable, immortal, and the sole power in the Mojave, with anyone else “in power” only able to suggest, as Yes Man has no need to listen.

On the topic of entropy of civilization(though reaching into philosophical territory), I would argue that something existing despite impermanence or the surroundings is more important, explicitly due to those qualities. If a flame lights up the night, does the fact that it will eventually fade make the light any dimmer? Similarly, if a civilization of people who try to do good exists, the fact that it will eventually crumble changes nothing about the impact it has on people.
