You speak of this reddit TV show as if it is relevant. It is also possible to measure quality objectively in many areas. I'm not sure why you went on that tangent.
I don't understand your notion that a game
can only balanced for at most a small slice of its players.
If a game feels unbalanced for a player who doesn't understand its mechanics, but balanced to a player who can employ his knowledge of the systems - can you then say that this game is only balanced for the second one? I'd say that it is balanced period, it just requires some skill and thought from the player.
I agree with your points about other factors to consider in consumables, that's why I like and recommended 7.62 Hard Life, as it has quite an involving inventory-Tetris to it. It's to the point that finding a chest carrier or a belt with pouches feels and more significant than finding a powerful weapon.
