So to counterpoint - 19 years in film & tv production, and this is pretty much a no-brainer day-1 purchase for us at *any* price.
...
I get annoyed when Apple fans (including me) loudly complain for years that Apple's completely neglected the needs of high end media creation hoping that high end home/developer/enthusiast gear would suffice (it doesn't) - and when they finally *do* create an obvious "Pro" system everyone's equally mad that it's not targeted at some other market that's better served by existing offerings.
While there are some who are complaining that it is overpriced, a number of posters (including me and the other non-film & tv production Pros) acknowledge that for the market it is designed for is appears to be reasonably price once configured. The point you are missing is that this other market you mentioned is not served by existing offerings. Apple continues to have a hole in their desktop lineup. The All in Ones (AIOs are not desktop although they fill similar needs) have the standard (iMac) and the Pro (iMac Pro). The laptops have the small (MacBook), standard (MacBook Air), and Pro (MacBook Pro). The iPads have the small (iPad Mini), standard (iPad) and Pro (iPad Pro). Only the Desktop line has just the small (MacMini) and Pro (MacPro), not standard size. This hole is where a large number of Prosumer and Non-Film&Video Professionals are. The new Mac Mini improved this as we can config it up to cover part of this hole, but there are still a number of use cases that this does not support.
The thing is, Apple is not a commodity PC maker. This is what got them in trouble in the early '90s in the first place. Their business model is hardware and software built as a unit featuring mac OS.
Should Apple make a mid-range tower? Maybe. The question is, what does it look like? And is there enough value for that market? There was actually a time when Apple did sell 10 different configs of the same model. Performa era anyone? And they were highly unprofitable. Jobs came, cleaned house, and simplified things to where they made sense.
It's very possible this high-end config will trickle down. The thing is, with hardware, the more use cases you have, the more the user demands things on the lower end of the market. It's always a race to the bottom. If you start at $2 or $3k, people would still be complaining about how terrible the config was, why they can't they offer a $1500 option, etc.
UP next at 10: people shouting to the rooftops why Apple doesn't license macOS.
While I agree that we do not want to go back to the 90s era Apple, even after Steve Jobs cleaned house there was always at least one mid-range desktop model available until the Intel transition. Even then the original Cheese Grater MacPro was a little above this, but still a reasonable stretch. This midrange was primarily the "Single-Socket" PowerMacs, with the Cube also being an attempt in this market. Where the Cube failed was that for $100 more I could have the "Single-Socket" PowerMac with all of the expansion options. It was easy math to select that over the Cube. The TrashCan PowerMac pushed the price out of the reasonable stretch range but also did not have the power that the Film & Video pros needed.
