Umm.. Urahara is not perfect by any means and he's a true scientist (meaning he experiments before drawing conclusions). Example, look at what happened to Masaki. Neither Aizen nor Urahara expected for White to choose Masaki as its opposite. In Aizen's case, he allowed her to live to see the turn of events that we know today. But what about Urahara? He had never treated hollowfication on a Quincy, however through dealing with the Visoreds, he was able to deduce that the opposite of a Quincy (a Shinigami) was the only way to stop Soul Suicide, just like a Quincy's holy arrows were going to be able to stop Soul Suicide on a Shinigami that underwent hollowfication. I just think Ichigo's human side hasn't come to terms accepting his instincts and embracing his Hollow side, which is going to be Ichigo's inner challenge from this point forward.
