Thank you for your analogy. Demand shapes supply is a capitalism fairy tale. For most markets you just can't buy what you want. Even if you would be willing to pay 2 to 4 times. You have to buy the mass produced sameness. We do not choose what there is to buy. In 95% of products and shops the supply dictates the demand, often with a simulation of choice. Look closely, for many applications there's only one or two products used nearly world wide. Often they are neither the best nor the cheapest. And don't get me started on the "choices" when it comes to smartphones.
