Very, very well put. Particularly point 2. It's rather like the Longino account of objectivity: hypotheses are made by individuals and are thus subject to bias; hypotheses are only made into scientific knowledge via the efforts of a diverse community. It isn't hard to generalize this beyond just speaking about…

I've read the Fountainhead, it was actually the first Rand I read. I also really enjoyed it for what it was; I was in high school and didn't know who Ayn Rand was, or what Objectivism was.
