And how much do you think the Humanscale mount costs that you would otherwise use? The Pro Display XDR is too heavy for a $30 Amazon Basics mounting arm or anything similarly cheap.
The Pro Display XDR is 7.48 kg and a $199 Ergotron LX Pro is rated up to 10 kg, so that's a fifth of the Apple stand's price.
And looking at Amazon.de listings, it's definitely possible to buy a cheap arm that's good for 7.5 kg. A "suptek Monitor Mount" is good for 10 kg according to the listing: https://www.amazon.de/dp/B0833NQ8CR
If you’re suggesting the only way to mount a display of that weight drives you into that price territory, that’s just ridiculous.
There’s huge monitors from other companies that come with mounts that handle more weight than that. Granted, it’s not some art deco CNC monstrosity.
I think the sibling comment nailed it: this is just a status symbol.
