We'll have to wait for Red to come out to really say for sure (since we don't currently really know what's transpired over the last 50 years), but in my opinion those 3 should actually cover the vast majority of people in the society. Going off of 2020's info, most of the governmental agencies and bodies have collapsed and/or have been privatized for various reasons, including the House of Representatives. At that point there are still senators (though many are corpos), as well as judiciary/executive branches, & the military. That said, these people represent a tiny fraction of the population who largely have very demanding lives in very specific areas that aren't Night City, so it is unlikely that V would be one of them. Furthermore, California is a Free State so it has even less governmental involvement than most of the US which reduces the likelihood of V having been one. Lastly, in this context these 3 options seem to refer to V's upbringing, and account for the "haves", "have-nots", and the "don't-give-a-damns", of those the civil servants will mostly come from the "haves" while military are largely led by "haves" officers and exploited "have-nots" for the rank-and-file, so even they will largely come from one of those 3 backgrounds.



TLDR: Yeah Civil Servants and Military Personnel existed in 2020, I could see an argument for including them as Life Paths in that time period, but even then they were a tiny fraction of the population & were probably corpos/street kids growing up themselves. After 50+ years and the currently unknown paradigm shift that is "Red" there could be even less reason to have those as choices.
