Please, don't forget that some of those "lazy ones" are living in places where there is little option to make iron or steel.
English characters, followed by Polish, have had the best resource supplies from the beggining of the game. Each new language group introduced in the game have had more and more difficulties to develop their industry,
And if ranged weapons had the ranged quality, like ability to shoot through windows or to shoot further while on a road or to shoot at ships that are floating outside a harbour, that would give them an advantage that would be worth using stuff on arrows.
In fact, if bows, crossbows and guns are not going to have ranged attack, it is a nonsense to implement ammo. It has been said before.
Crossbow should be terribly bad melee weapon
Any ranged weapon should be a bad melee weapon.
Currently, any kind of weapon in Cantr is of the same type "Cantr irrealistic weapon". There are no ranged nor melee weapons in Cantr.
Why not just make three kind of arrows?
Just because there is no range attack in Cantr, so it has no sense to use arrows if you can't throw them. Very cheap arrows would be less annoying than expensive ones, but all of them would be stupid and unnecessary.
While the combat system remains unranged, all this discussion is as pointless as the pregnancy topic with baby characters being not allowed.
