Economy of scale - F-35"D"?
Scale up production to bring down the unit cost - but who can buy many hundreds, if not thousands of these aircraft?
Produce a civilian variant that shares a lot of the expensive components, and market it to the likes of Amazon, DHL, UPS.
After all, if the aircraft is a doddle to fly, no need for fast jet pilots - there are plenty of out of work commercial pilots who can now be employed as delivery pilots.
