The cost of creating things on this side of Dusk doesn't seem to change significantly with the size of the item. It might increase slightly, but not excessively.
Something like a Firmament Wheel only requires a mere '25 merit points.' Uh, though this is limited to this world, such a price is extremely cheap in Zheng Yichen's eyes.
Zheng Yichen casually asked Dusk about the merit points required to manufacture a photolithography machine here, and Tia quoted 3 points, which is not a big deal.
It seems that nine photolithography machines would be worth one Firmament Wheel. In reality, a world capable of producing photolithography machines wouldn't think of manufacturing them here at Dusk.
If one were to manufacture photolithography machines here, wouldn't it be like exchanging merit points for money? It's worth millions, yet which Dusk mercenary uses merit points to exchange for money?
