Least wasteful is still wasteful, you are missing the point. How many people need these cameras, as opposed to wanting one based on marketing? Why are these people not buying all the used D70's on the market? There are 700 of them on ebay right now. 500 D80 and 500 D90's as well.

They would be better off carrying around a Cannon SX740 for 1/6 of the price. If you cannot take a good photograph with that then you will not take one with a Z9.

People buy these cameras because they have the money that other people do not and they think the camera makes the photograph. It is like thinking the paintbrush makes the painting.

I am still using my Nikon D4 (2012), but they simply don't make parts for it anymore. These are mechanical devices, so they will simply wear out with use (I got pretty much the last spare parts that existed in my country when it last needed servicing).

I find it a bit sad; I could understand it for a dinky plastic camera, but with a flagship device, why can't they just make a bunch of parts and put it on a shelf for 30 years?

Eventually I'll probably buy a mirrorless; but I guess with a shutter count of 196 613, it's had a pretty good run…

How about not buying a camera at all and using the camera on your phone? But I had a Canon point and shoot that lasted 6 years so I have no idea what you are talking about.
