Which brings a slightly unrelated note: people seem to be blissfully unaware that you need less than 9mpix for a 12x9" 300 dpi print or that the zoom lens they bought with the camera has sharpness that effectively limits the resolution to 5-10, maybe 12 mpix if they are lucky. But megapixel count is easy to sell -> race for more megapixels -> smaller physical pixels -> more signal amplification needed -> more noise / general lower photo quality.
64Gb is completely unnecessary for photography. Photographers don't even go over 16GB.
You don't buy/rent a camera you can't afford to process images from just like you don't buy a car you can't afford to service and you don't buy a house you can't afford taxes for. Or if you do, I have little to no sympathy.
The computers often are owned by the company renting the gear, where the end customer pays for the camera rental.
So it's not so simple. And one thing - go easy on using the word idiot... I work with some very smart people who fit your description of idiot on a regular basis.
If it's really true, then your pricing is clearly wrong.
Absolutely no one that owns one of these professional cameras uses them with non-Xeon CPUs.
Really the only use for greater than 64Gb for non-Xeon CPUs would be student animation or machine-learning projects.
