We are using different definitions of the words "intelligence community". To me, if you have a clearance then that makes you part of the "intelligence community" regardless of whether your salary is paid by NSA, NASA, a defense contractor, a national lab, the Army, a university, or whatever.
If your definition of "intelligence community" includes NASA or random low-level soldiers just trying to keep their planned operations out of the hands of their adversaries, then I'd submit that your definition of "intelligence community" is functionally useless. Just say "clearance holders" if that's what you mean... there's already a very precise definition of "intelligence community" as it pertains to the U.S. anyways.
