I kinda lost you. I don't know, how you came to that conclusion from what I said.
And if everyone understands that the game is about overcoming challenges and is on board with it, then they'll make in and out of character decisions that lead to challenges to overcome. If someone wants to abuse, then they aren't in for the challenge -- and then why are they participating in such game at all?
If the game is about overcoming challenges, then it's everyone's job to create challenge, just like in a comedic game it's everyone's job to place set ups and deliver punchlines.
I'm just saying that certain people if given free reign will do things not even remotely allowed by the rules. Fortunately they're rare.
Maybe a better example (I wasn't the DM but it's still relevant) would be the guy playing a cleric of Odin that thought he could find anyone or anything any where any time because "Odin sees all" even though he was not even casting a spell or asking for divine intervention. This was to find the phylactery of a lich that had achieved basically demi-god status and we had (at that time) no idea where to even start.
As far as why some people want a "I win" button they can press at any time? I have no clue.
