What is the argument, then? My point is that it seemed off because it was still trying to force a way to find stealth for large containers that have to move.

Remove the need for large and movement, and you get different constraints. No need to rely on "fundamental physics limitations" to point out that it will be difficult. And yes, as you add in more constraints, you get more difficulties. So, if you want completely clandestine deployment, that will be far harder. But nobody would be surprised to learn that a military base has lots of latent defenses. Why would this be any different?
