If someone starts targeting the USs nuclear arsenal with nucs the last thing they would be worried about is civilian casualties as they will probably be targeting the seat of government and major economic centres too. You are missing the point that SSBNs are inherently survivable and likely would only ever be caught in port if they were undergoing maintenance, other wise they would be crewed and ready to go or already on patrol and invisible.
I know TEL based ICBMs are of interest to you but that doesn't mean they are actually, better, cheaper or somehow more suitable than the in service options. You say you would like to be proven wrong by someone who knows more but you have chosen not to listen to the defence pros who have discussing this with you, some of who have considerable experience in submarines, armour, distributed operation etc. I feel if someone came on here and identified themselves as a boomer commander you would say they were biased, if an army / air force ballistic missile expert told you that using TELs was logistically challenging you would probably say they weren't abreast the latest developments etc. or were weren't up to speed on what the Russians, Chinese, etc. are doing.
I get the feeling this is your pet idea and you don't want to let go, I understand this as I believe the RANs need flat decks similar to Japans, but clutching straws and telling def pros how to suck eggs is just getting the mods off side.
