I'm not aware of any military that deploys a precision marksman without a spotter. That makes a precision rifle a two-soldier job. .50 caliber machine gun? two, maybe three boots? Squads will have members with DMRs or LMGs but they aren't suitable for the same task -- they just extend the capabilities of the squad.
Extend that to thinks like fighter jets, nukes, comms, etc. etc. and the actual threat of any of those is drastically reduced outside the crazy people do crazy things category of events, and even then, you're going to need a big group of crazy people.
The replacement and actual threat already exists and was popularized in the Middle East in the 70s and arrived here in the 90s but it isn't sensational but I'm not confident I wouldn't end up on yet-another-watch-list by saying it explicitly. So, yay, freedom.
What a wild straw man argument. On the one hand, I generally agree with you. On the other hand, I am fairly confident I wouldn't trust anyone to decide for me what limits there are on "revision or excision of bad ideas".
So much of what you argue for relies on trust- trust that we are all working towards a common goal, primarily. However, there really doesn't seem to be a clear path forward when both sides assume the other side is arguing in bad faith.
