Roger should've been able to continue with the PF name if he wanted. He should've been able to because he was, in essence, Pink Floyd. He wrote nearly everything from 1969 onwards.

And no, I'm not discounting contributions by Mason, Gilmour or Wright. Without those three (Gilmour in particular), Pink Floyd certainly wouldn't have been the same.
