By that metric though, if we don't build the GALILEO as a mainline combatant, we'll just need to build something else for that role right now, which will also prevent us from building a new capital ship when war comes. I think it's far more reasonable to build these as a heavy cruiser, and then perhaps design an explorer we build one of every few years.
Why do we need to build something else for that role? The Galileo is still worse than a Sagarmatha as a mainline combatant, and the Selachii are still very competitive. Our last three projects have all been to support offensive operations in wartime. Our internal security, on the other hand, appears to rely mostly on Cygnus, which is at this point over fifty years old. It has comically low average damage, and if we're expecting our convoy escorts to need to fight BoP it's totally screwed.
To summarise:
- Torpedoes do not effect the final cost rating of the ship.
- Torpedoes do not really effect of ships we will build.
- In wartime, torpedoes would theoretically slightly reduce the number of Selachiis we could build if we were Galileo-maxxing in our wartime build composition. But realistically we would not do that, so it does not actually make much of a practical difference.
- It would actually be a serious issue if we tried to build the Thunderchild Mk. 2 whilst we were still building Galileos.
So the Infrastructure Cost is a real cost, and in a different scenario, could be very relevant. It's just not a cost in this specific situation we find ourselves in right now, when we have a lot of Selachiis, want a workhorse line cruiser, have just finished a war and hope not to be in another in the next five years (touch wood), and are not planning on designing a dreadnought or explorer in the next five ears.
I pray and hope that this can put the cost argument to bed, and people can find a different reason to justify their vibes-based dislike of the torpedoes, like losing a slot. This is at least technically true; even if the cost benefit is clearly in favour of an entire rating grade in a core mission requirement versus an auxiliary capability.
Starfleet is presumably not going to be putting mainline warship armament onto these things and then deciding that they're not actually going to put them in the fleet. But our fleet is fine. We can't stop building stuff for our fleet; Of our past five projects, three of them were for the fleet, one was a intra-system patrol boat, and the oldest one is the Cygnus:
Cygnus-class Utility Cruiser [2167]

The other ship we have for rearline security is the Curiosity, which this is
supposed to replace:

Warp (Cruise): 4.9 (117c)
Warp (Max): 6.9 (328c)
Operational Range: 58ly
Industrial Cost: 19 (Civilian) + 12 (Starfleet)
Like, Sayle explicitly said it's not really an issue unless we were building the Thunderchild Mk. II for our next class. Which would be silly, because... we aren't going to do that.
How are we going to sell this to Starfleet in the next war? Just don't build more of those heavy cruisers, let us design a new dreadnought instead? The problem is not that they're expensive now. They're basically free,
right now. Then they will be very not free when we go to war and we have to pump out as many of them as we can. We've already compromised the design with low agility with the understanding that it wouldn't matter in the roles it was intended to fill. Slapping on a warship armament at the last second without being able to guarantee that Starfleet won't just keep pumping them out during wartime seems unnecessary.
I don't hate the torpedoes, and being able to put a bunch of great sensors on the frontlines in a war against the Klingons would be nice, but it runs the risk of Starfleet forcing this ship into a mainline warship role that it was not designed for and leaving our rear lines vulnerable, all to bulk up our fleet which does not need to be bulked up right now.
