I disagree. It is good to have more than one design. It is not exact duplication so alternative approaches are taken. We have more than one design if one proves flawed. We avoid creating a monopoly.
We could maximise economies of scale by having one car manufacturer that made a small number of models. No one would suggest that is a good idea.
Even the Soviet Union did not go to the extreme of having only one design for every possible product.
