But it could have made an effective counterpoint to Marcus' war machine approach, that more weapons doesn't mean better or more secure.
Mostly because Marcus fired his more and better weapons first from is more combat oriented vessel while Kirk tried to use the Picardian talk your way out of a fight maneuver against and opponent who wasn't having any of that and promptly blew the crap out of him.
Oh, but how was Marcus defeated? By beaming over a superweapon in humanoid form to covertly take over the ship.
Our message for today, kids: at your Wheaties, wear black, and try eugenics for a change! Starfleet shouldn't be a war machine, it should be pro-CIA/NSA. Don't forget your cloaks and daggers
