My main point was that you pay for it regardless. All the things you list i can also do with a cable i simply purchase seperately. But the difference here is that i can either choose not to buy one, if i don’t need it. Or purchase a specific one e.g. a very long one, if i prefer that over the standard short one.

I doubt most manufacturers would lower the price when stopping to include them, but they might delay raising it for a while. In any case i think the economic mechanism (at least in an idealistic setting) is logical.

I don’t think it would logistically make sense to have versions with and without accessories included, since that instantly doubles the version count. But most if not all places that sell phones also sell cables/chargers. So in that way the choice already exists.

That said i think this line of thinking mostly works because we have standardized on USB-C for quite a while now, so the assumption that most people already have access to a cable is valid. This would be different if they’d require specific cables like e.g. my garmin watch does, which you wouldn’t normally have and that you’d likely purchase from the same manufacturer. In that case seperating them might have the opposite effect in making the price to consumers less transparent.

Also i could get behind the idea that not including something like a cable would require a prominent warning lable that “a cable or wireless charger (if applicable)” is required for longterm use.
