That's true, but how many people come to the market eager for all the strong points it offers? And willing to overlook the weaknesses?
As you say, the Apple Studio Display is a product with a unique combination of offerings, and that might be the best match for some. I could see it being pretty sweet for a Mac-only user in a dorm room or small apartment, or with a strongly minimalistic aesthetic.
And that would be people who are fussy about color. Photographers, graphic designers, etc, etc. IMO, it would be overkill in $$$$ buying it for its physical aesthetics. But that's just me, not caring about aesthetics.
I've had my ASD for almost two years. Before that I used a 27" iMac. Being a photographer who prints a *lot* of photos, after I post process an image file in Lightroom, I want my prints coming out of my printer to look like what I see on the display. With my 27" iMac I needed to use a color calibrator device on the display in order for that to happen. And even then, some times I needed to re-adjust my edits, varying color/brightness/etc and make additional prints to eventually get the print looking right, wasting printer paper and expensive ink in the process. I'm guessing that's due to display aging, and needing to recalibrate it once in awhile.
When I received my ASD (and Mac Studio computer), I simply selected a reference mode from a list in ASD preferences, tweaked it a little, and saved it as a preset. You can create and save multiple presets, if needed. I haven't needed to adjust it in the two years I've owned the display. - it has been extremely stable. Would it be better with a color calibrator? Possibly, maybe not. I'm super pleased with my results now.
Every print I make comes out of my printer looking like what I see on the display. I can make a print, let it dry for a day, and the next day mat and frame it.
