Bitcoin attracted a lot of people with a well established background in academic and/or Silicon Valley. These guys are used to building resumes, not hiding their identity. There is also this culture of transparency in the FOSS space, which extends to using your real name. And unless you are as careful as Satoshi, it's unlikely you could effectively hide your identity being active in this space for a decade.
