No, I argue it's exactly what GP says. Consumers choose out of what's available on the market, not out of space of all possible products.

When purchasing complex goods like cars (or smartphones), there's way too many things to simultaneously optimize for, and enough confusion (mostly intentional) about relative performance, so most consumers focus on few major indicators like price, availability, cost of ownership, appearance, etc. Few people are going to trade on those major points to optimize something more specific, like lack of touchscreen (or having a headphone jack), so there's no meaningful market feedback on this, and vendors are free to dictate the choice to the market.
