I still agree that all tech cost comes down with time. The more common something is the less pricy it will be OR there will be cheap alternatives at least. Just think of the first computers lol they were so ridiculously expensive!! Today u will find a processor thats as fast as a 100.000$ computer in a mobile fone.
You can also get a cheap car. Or a cheap camera. Imho there are more cheaop alternatives nowadays to get good photo results than were available at the beginning of the 35mm film era.
I guess its something like at the dentist. The actual material cost isnt so high but its other factors that can icnrease the price a lot.
p.s.
please FF camera for under 1k$ w/o video mode, wifi or such

Reduce it to just what we need. Aperture, shutter speed, iso.
Uhh sounds like Leica....lol
