I understand your pedestrian frustrations, but what you don't seem to understand is that the risks to government and military, i.e., your defense, are wildly exponentially larger and far more consequential than you quite clearly seem to appreciate.
Sure, there are many under and even unqualified people in positions that they are overpaid for, but that's largely more due to HR policies dictated by Congress and nepotistic corruption. Besides, those people who you think aren't quite possibly are incompetent, are largely doing a job that in all reality doesn't need to exist and is really only a position in order to fabricate a job for a vet or make various people money for various reasons.
The reason you see and experienced such frustration with the immovable and static nature of government / military networks is simple a matter of real national security. Reality is that on a geo-political scale that you can't even imagine exists, there are real reasons for concern and anxiety that is only stoked by the paranoia of our guilty subconscious conscience due to our own nonsense actions and behaviors.
You have freedom in the private sector, because ultimately, if a company fails, all it means is that you find another job at some other fabricated, imaginary, lofty, con job of a start up that is pumped out of "Silicon Valley" on a quarter hour basis. Failure of a nation, because some lackey wanted to experiment, means a real threat that you are incinerated, lines up looking down at a mass grave, or vaporized.
Because at the core, no matter how advanced we want to perceive ourselves in spite of all the evidence to the contrary, humanity consists of various troops of primates which a rival troop will try to kill, pillage, rape and steal our women at the first chance that presents itself as perceptually cost-benefit positive.
