A handbrake cable has one moving part and consists of a steel cable and stamped steel level arm with a spring return. It costs almost nothing to make, almost nothing in materials. It's an incredibly cheap assembly.
Motors require much more material, which is made out of more expensive metals. It's not a cost issue. If it's a cost issue, why do the cheapest cars in the world all use mechanical hand brakes?
If it's a cost issue, shitboxes built down to sub 10k prices would have electronic brakes, but they don't. Because it's significantly more expensive than a stamped/braided steel assembly made out of recycled cans.
