Same reason we have more car colors. It’s more expensive. But we value variety more than that marginal cost. That doesn’t change that producing one costs more than the other.
(There is also a massive difference between consolidating fabrication and consolidating construction. Developments work because you have one team doing a similar set of tasks at the same location repeatedly.)
