The other party was arguing that cupidae in the present era did not engage in cross-border interaction.
Yes, it's entirely possible that Cupids themselves do not engage in meaningful cross-border interaction (as they are not incentivized to), but they are affected by
humans who do (previously being humans themselves and existing on the same plane as humans).
But the constraints were not primarily physical or technologic; they were institutional.
I don't see the reason in arguing why it wasn't a combination of all three.
As far as has been shown, they make decisions as consumers, not as producers. They cannot select what is not an option.
As far as what the Cupids are able to select, we don't know. Is it the Cupid's knowledge of weaponry itself? Can a baseball bat "count" as a Cupid weapon? This is another area where it's not worth extrapolating so much since we don't even know how the Cupids exchange Karma into weapons. Is it the pigeons working as intermediaries or is it another type of "listing board" like the boards of Target Files? The "poofing" of weapons in and out of existence already point to a Cupid's selection not being so limited, but it's not enough information to work off.
Again, the argument is over whether the Japanese cupidae are effectively cut-off from the cupidae elsewhere. My point has always been that their choice of gear provides no support for a theory of isolation nor has other support been found. Note that we have no knowledge of when-and-if firearms were adopted by cupidae outside of Japan.

They're not any more cut off from other Cupids as humans are, the question is whether Cupids bother to engage in cross-cultural exchange when their "lifespans" are shown to be 1 year if you're working fast and there's no incentive to work outside of your nation's borders. I think you're splitting hairs over a specific part of one argument/theory that's positing the reason why Japanese Cupids weren't using firearms at large earlier than Chiyo's time (which is shown in the Ch 0 prologue to be a time where bows and arrows were the standard) despite the firearm exchange starting in the 16th century is due to Cupids being more isolationist than humans.
And the theory that the Japanese cupidae are operating and governed in isolation is not merely a stretch, but a very great over-stretch; it has nothing approaching peculiar evidence. If we saw them deciding what gear to produce, then the theory would be on firmer ground.
Well, it's more like the Cupids haven't been shown to be governed
at all. That's notable in itself, all we have shown is that pigeons are sort of middle men/one-way messengers between the Goddess and Cupids and that the only passage of their rules and history has been via oral tradition so far (not the Target Data Records don't even have instructions on them). I think the conversation is worth revisiting when more information is revealed.
