Because you do not understand the basic manufacturing business model. New technology and products require R&D; which is a lot of times off-set by higher cost of goods at the beginning of a run. Plus, because it is not in high demand, yet, means they are manufacturing fewer products to start with. Fewer runs means the products generally cost more to produce because they are not buying components at the same level as they would for something that is mass produced in large volume to meet consumer demand. That, along with the constraint on supply chain and certain parts that may be used on motherboards (I know for fact capacitors are having supply issues, I see this a lot in the HT market right now and since last year) adds up. The inability to source supplies and parts because manufactures are having issues with raw materials and even getting the items into ports and such, causes an increase on overall cost of goods. Therefore, all of that cost is added in to the cost of the consumer product.
That's not even getting in to the lack of overall parts from last year and the skyrocketing sales on PC and Laptops due to WFH and students being at home. This would be why you saw CPUs selling out and above MSRP as well. Low quantities and high demand.
How hard is that to understand?
