For the same reason that Satoshi Nakamoto is likely one person and not a group, so is Banksy. too hard to keep a secret like that for as long as it has been. I'm surprised we haven't seen more people claim to be Banksy, as we have with Satoshi but perhaps it's easier to profit from pretending to be SN than it is by pretending to be Banksy.

Three may keep a Secret, if two of them are dead
