A modern ICBM is able to hit multiple targets using multiple independently targetable reentry vehicles with an accuracy of 150 meters and very high reliability.

Weapon systems reliability is not same as for space launch. The make up for failures with numbers. Also the weapon system payloads are passive for launch.
The Trident missile system has had 135 consecutive successful tests. That is pretty much the best space launch systems to date.

Launching with fewer people reliably is clearly possible, as shown with your example. Its the kind of new technology and designs that NASA should be working on. It's a clear tip-off when Jim slams questions like this without offering any significant technical rationale.

"50klb spacecraft into LEO" is significant technical rationale.Trident SLBM are not space launch vehicles. And RV's are not spacecraft. or even manned spacecraft. It has nothing to with "new technology". It has to do with complexity of the task and the complexity of the payload. That is the difference between the vehicle.,
Sticking with SRM's.You have excluded the team to build up the trident, that is not part of the submarine crew nor the ICBM launch teams for Minuteman. Look at a Minotaur launch team, it is in the 40 to 50 range (including the techs to build it up)
I'm asking what's possible by way of examples that show it can be done, reliably.
And yet SLBMs have independently targeted payloads and so are more complicated, at least in one respect
I have a question about lattice structures on interstages. It has been my understanding that these are designed to dissipate any fuel or oxidizer that may leak from the upperstage.I see a simillar structure on the Agni-II, which is a solid fuelled IRBM. Can anybody explain why this design was used when there is no chance of fuel leakage. Does it have any other benifits.
If that were true then Atlas and Titan could never have been converted to space launch systems.
