If you activate the Securitron army (rather than destroying it), the Securitrons keep order after the battle for the dam. If you destroy the army, then there is anarchy. In the Independent ending, Yes Man says that he's going to "go away for a while" to reprogram himself to be "more assertive".
I don't believe that House offers all that good an option for the wasteland because I personally agree with Caesar: people, not gadgets, are the answer. House's belief that he can just buy his way to a better world, or that it isn't necessary to lay down rules for society, is foolish. You can't build your society on gambling then just mill that cash into space travel. What House is really describing is basically a capitalist North Korea, where there is no economic or scientific progress outside the Dear Leader's pet projects.
Caesar changed people; the Legion may fight amongst themselves but the ideas he brought back to life will live on, just as those same ideals always have. If House dies, his legacy will be as evanescent as any other dead capitalist.
I also looted the Sierra Madre Vault, but I didn't sell the gold. Instead, I made a little money pit on top of the Sink, and threw in some chips, coins, and currency for effect. After beating the game, in Aestu style, meaning getting as many perks as possible, speccing to nearly cap every stat without cheating (other than the two Dead Money exploits), acquiring each and every unique weapon, armor, and vanity item (e.g.,
three guitars, two copies of Scripture, all the
imitation meat pies, pre-war steaks, and every other unique food item, as well as every mutilated body part and brahmin skull I could find), I spent about three hours neatly setting up the quarters in the sink.
Actually, I seem to have misplaced my best save file (think I accidentally cut instead of copied at some point). Some of the cosmetic stuff I did hasn't been done in my latest save.
Maybe I'm RPing too serious.
