In closed space Haruhi has absolute power and Itsuki gains power. In fact theoreticaly Yuki could be rendered totally powerless in some forms of closed space.
Rouyko had to alter the nature of every building on earth to create an *imitation* of closed space.
An existence is only present if somebody acknowledges it. If Yuki undoes the SDK characters presence, then alters the minds of everybody who ever knew them, it would be like the same as them not having existed in the first place. Kind of like the torches in Shakugan no Shana. Similarly, Yuki can affect reality in ways that allows her target to be rendered in ways she pleases. Kind of like how she made it so that SOS-dan could somehow suddenly start hitting homeruns by "hacking" into their data. Or how she affected the reality in another episode because she was "lonely." (I forget what happened)
Ryouko was a back up of Yuki, which means she was at least as capable as Yuki was. She wasn't a mere imitation. The two shared very much the same powers. Yuki was just smarter. And she *was* powerless in the closed space that Ryouko had created. As stated, everything in that space allowed Ryouko absolute power, but with some prep-time, Yuki managed to beat her.
