What I am getting from the "anti-fullbring clan" is that there's really no use for the fullbring since Ichigo can get his powers back by being stabbed. Yes, he was stabbed in chapter 459 by Rukia again. Yes, then he got his sword back. But anyone noticed that the sword is different now? i.e. Zangetsu is different now.
Also, the fullbring training was to awaken the innate shinigami power (reiryoku?). Rmb that Rukia said that Ginjo only stole the 'top layer of Ichigo's power' in Chapter 460.
Lastly, it has always been Urahara's style to wait for the "something" to happen before taking action, yes?
