Fair point, but this isn't a cheap bike, so maybe at least make the option available?
I also am not certain on the exact reasons why internal gear hubs and belt drives are more expensive. I imagine manufacturing those hubs are more costly just by the nature of their design. It also used to be the case that you needed a specific frame built for a belt drive to run one, but they make breakable belts now so that's no longer a huge restriction.
I have heard in Europe where bike commuting is far more common in the US where I'm living that belt drive and internal gearing are more common, but this was hearsay.
Internal gearing is generally a lot heavier as well as being more expensive. Looking at the priorities on this build, I suspect that was as important as price.
