Connectors come loose, which makes them dangerous.
They are uninsulated points that allow water and material ingress, and can partially or fully pull apart, causing arching. Which can cause combustion.
This is the main reason these are dangerous, which the majority of this entire thread misses. The added length or connector resistance is somewhat negligible here unless you’re daisy chaining long conductors, which often isn’t the case for in-home extensions.
I think you’re being intentionally obtuse here and betraying the spirit of the question?
Your meta analyzing the question instead of just taking the questions as it is, and in the process failed to actually address the core question. It’s a hypothetical scenario where most of our radio communication is jammed and unusable.
The mechanics of how the question got there don’t really matter, that’s not part of the question, it’s pointlessly pedantic to pick it apart. Just imagine the scenario with the mechanics you can consider plausible for such a scenario, and roll with it 🤦
