Your line of argument relies on this -
Axiom: While, in the past, gov't organizations were quite capable of performing the largest, most complex, and most critical technological tasks that society faced, things are somehow Different Now - and only non-gov't organizations (very preferably for-profit corporations) are now capable of such things.
But what is actually Different Now is this: Our ruling classes de facto decided to reduce the gov't's core competency in a part of national security - because outsourcing those capabilities to for-profit org's was far more lucrative for them, and the nation seemed secure enough that they didn't much care about the downsides.
Humans are very responsive to their social environments, and its structure and unwritten rules. Setting the "Non-corporate" bit on the org that a human works for does not magically reduce what they are capable of. Linus Torvalds actually is the creator and BDFL of Linux. Even though he is an individual human - not a corporation, nor a secret front for one. The mathematicians who completed the classification of finite simple groups ( https://en.wikipedia.org/wiki/Classification_of_finite_simpl... ) over decades and centuries completed that massive task while generally working individually or in small groups, for wide array of colleges and universities.
