To explain Exegol another way: Say you’ve trapped me in a room and locked the door. I have the key to escape in the room with me. If you want to stop me from ever escaping, does it make more sense to destroy the key; or does it make more sense to take the key for five minutes and then give it back to me?

That’s my point. It makes more sense if their goal is to just prevent the means of escape completely, rather than “temporarily stall them, and then hope that the miraculous civilian fleet that may-or-may-not-come-at-all will show up in the nick of time.” (“You’ve pinned the survival of the Resistance on bad odds and put us all at risk!”) The film is already halfway there, between the general concept of the Nav Signal, and everything Finn does in the battle. And we can close the remaining gap very, very easily.

As a proof of concept, here is the entire Exegol battle, with just the following bits removed:

Cut Poe saying “for just minutes.”
Cut Finn saying that the Fleet only has to stay stuck on Exegol “Till help arrives.”
Cut Poe’s “but not for long.”
Cut Poe’s “last chance.” (This one could be smoothed out more.)

That’s it. That’s all of the changes it took. Now the Resistance wants to permanently destroy the nav signal, and thereby trap the First/Final Order on Exegol. That’s the goal. Makes perfect sense to me. I can’t understand how anyone would come up with the other plan as a logical course of action, and I’ve basically changed it around from that just by cutting out some of the semantics.

Heck, if you’re really worried, we could even swap around one of Poe’s lines a smidge to clarify the point even further:
