How does this make the
game any better if you are making shit up while you play it?

This is one of the most stupid things I've read for a while.
Because the game is canon according to Bethesda whether you like it or not.
Now which version would you rather have as a canon part of the series; the version with giant robots and giant super mutants and lulzy nuclear explosions and saintlike BoS, or the version where all of that was a virtual reality simulation full of propaganda?
Also how the fuck is that "making shit up"? If it makes sense it's not "making shit up". Many people believe that Decker was a replicant in 'Blade Runner' even though that was never directly stated to be truth, is that "making shit up"? Many people believe that the bluish world of Zion in 'The Matrix' was still part of the matrix itself, even though this was never directly stated to be truth, is that "making shit up"? No, because there were hints dropped throughout both movies that this was the case.
It can also be argued that there were several hints dropped throughout Fallout 3 (albeit, unintentional hints), that point towards the entire plot being a virtual reality simulation. For instance those virtual reality pods are prominent throughout the entire game, and one of the DLC is about a propaganda-filled virtual reality simulation about training to be a soldier. Is it honestly that difficult to believe that Fallout 3
itself is just a BoS version of Operation Anchorage?
Face it, some fan theories can make things better.

It's the same as when someone LARPs that his character "takes a shit once a day" by hiding behind a house, unequipping his pants and if some guard accidently sees him doing that running around like a madman (as if the AI would care/recognize). Yay, let's play pretend things out of thin air!
The fuck? No it's not. The concept of a "theory" is not unique to games.
Cameron creates Ferris Bueller in his head. Zion is part of the Matrix. Decker is a replicant. "James Bond" is a code name, not an individual. Every moment of Inception is a dream.
How the fuck do any of these have to do with LARPing? Theories are not the same thing as "pretending".
Edit: Your entire argument consists of "How dare you try to make sense of the pile of shit that is Fallout 3? I hate it, therefore you are not allowed to prove that it's possible for the game to be consistent with the rest of the game series' universe."
