> Drones and defense have nothing to do with expense
I would disagree? Look at Helsing, the german manufacturer of loitering munitions, and its direct competitors who are trying hard to get per-unit costs way down. Without even mentioning the myriad of Ukrainian manufacturers who are building cheap and cheerful things under $10,000 per unit (or even under $2500 per unit). There is a very real push within all NATO militaries now to basically copy many of the capabilities the Ukrainians have built in the last 4-5 years.
Not saying that we won't still have lots of huge dollar items and massive programs like the AGM-158 JASSM, but there's a reason why the US paid a company to basically clone the Shahed-136 as the LUCAS at under $50k per unit.
Volume unit costs matter a lot. What matters less is cost during prototyping and development, where speed to iteration becomes way more important.
I absolutely agree, if you have just a few people who are each paid 180k a year sitting around waiting for something to arrive because the low-quantity prototyping vendor is slow, it's not the best use of resources at all. One of the reasons why certain companies spend a lot of money buying their own laser sintering 3D printers for low volume test-fit protoypes in the aerospace industry, or invest in their own small-scale CNC stuff to do similar.
