Those theories however, have something that yours (a couple of posts back) lacks: internal consistency.
I didn't fully articulate it.
I think the striving for "power" (or "presence" to use something more ethically neutral) is Se. You seem to be into socionics, IIRC, and socionics describes Se the same way. Se is about fully grasping your environment. I don't really see how this relates to Fi, as the INFPs I've known were not about that. If they were ever control freaks, it seemed to be more about harmony with their inner state... they didn't like the reaction to something they were having, and seeked to change the environment to bring it more in line with themselves.
Se is concrete, and seeks to navigate actual physical environments correctly. INTJs seem to place some importance on this, and it seems important to their self-image, just like Fe is important for my self-image.
I agree that Fi is important for INTJ's, but the more competitive nature of the INTJ is not because of the Fi, but because of the Se, I think. Although, I wonder if it's a situation where Se provides the ability to control environments, but Fi provides the will. I can see why Fi would seek to change the environment, to bring it in line with itself. I suppose Se is important as the means for doing this.
You might have a point here. Interesting.
I do think there is something "aspirational" about the inferior function, it's the function that people are going to most want to "prove" something to others with.
"See....I'm not a cold-blooded robot.... I care about poverty and crap! "
"See...I'm not an overly-abstracted nerd... I like gangsta rap!"
That's my main point... really. INTPs want to be engaged and invested and passionate, INTJs want to be powerful and a force to be reckoned with.
Introverted intuition has nothing to do with physical power. Se does. Fi might generate the will to have that power, though.
The real reason I think Snowden is INTP and not INTJ is because he doesn't really want to be the one who makes the calls. He doesn't want the power. To me, it seems as though he feels as though the responsibility fell on him, and he was the only one who could act.
